327J: Late 50’s/Early 60’s Long Island NY Grade School Reader

I’m looking for a book I remember so I can reconnect with the late sister I never knew.
I was born in 1965. I have one living sister (June, born: 1957) and one who passed away before I was born (Susan: born 1948).
I think the book belonged to my sister Susan, who was killed by a drunk driver in 1963. My parents couldn’t bear the pain so most of her things were not kept–too many memories. A few schoolbooks were left in the basement. I remember one especially…it could have been Susan’s or my other sister, June’s. I hope this information provides you with an idea of the time period/range of dates involved. Fairly positive it was before the mid-1960s.
The last time I saw it was a very long time ago, probably around 1973. I’ve been looking for it ever since. It was a grade school reader, blue boards…would have been used on Long Island, NY, in either Suffolk or Nassau County. I believe the first story was about boys vs. girls building a tree house. I think the girls put curtains, etc. on the windows. There are pictures throughout the book, but I don’t think the reading level was too young (not Dick and Jane, for example). There was also a story about a circus with an illustration I clearly remember of a lady in a tutu standing on the back of a running show pony.
I don’t remember much else. I think it was fairly thick, and the standard size for a hardback book.
Our address in New York was in St. James, NY, but my sister Susan only lived there for about two years. Prior to that I believe my family lived on Duffy Avenue, Hicksville, NY. This might help with the school districts.
If you could find the title for me, it would mean the world, because I could try to track down the book. When I was child I liked reading it, but I think when my mom saw it, it was either given or thrown away because it was too painful for my parents. Today the book would also be a connection to my late sister — even though it wouldn’t be her copy, it would still be something she read.
Many, many thanks. I’m sorry I can’t provide more information.

292X: Animals he could make small and take home

I have no idea about the title of this book. It is one I read (and owned) in my childhood. I think it was sent as part of my subscription to a children’s book club–perhaps Children’s Literary Guild. Probably I encountered it between 1940 and 1946. Plot was about a child–I think a boy–living rural, who went to a visiting circus. There he encountered animals who he could somehow make small and take home with him.

288F: Boy in pajamas chases illusory tiger (Solved)

I’m looking for a children’s book I read in the late 80’s. From what I can remember it was about a boy in pajamas that is chasing a tiger or other large cat, but pretty sure it wasn’t a lion, I don’t remember a mane. The tiger was hidden on every page, in the background such as hidden as a pattern of stars in the night sky, a symbol on the border of a tent, or made of vines. As far as the setting I believe it was in the boys’ dreams. The book had a very surreal feel to it, and the book was filled with illusions. These illusions made a thing look like another, like a strongman made entirely of things from the sea, like seashells, crabs, etc. Here’s an example of the type of illusions I remember in the book

They do visit a circus at one point, because I seem to remember one page outside the circus tent, and possibly one more. But the book wasn’t entirely centered around the circus, it felt like they were just passing through. The circus is a google trap though, there are lots of kids book involving the circus and a tiger, and I haven’t found one yet that matches what I remember. The book is definitely not I Spy A Tiger, Heart of A Tiger, Riding the Tiger, A Lion in the Meadow, A Tiger Took Me to the Circus, It’s a Tiger, or Come the Terrible Tiger. Please help! I’ve spent hours searching on the internet, but I keep getting nothing.

226H: Short story collection

It was definitely published before 1994, possibly published in the 70s/80s.
It was a collection of short stories printed in paperback, my copy was missing the from and back and the first page that normally lists the title and publishing info.
Each story was like 5-10 pages with some detailed black and white drawings on occasional pages.
There were 5 or 6 short stories in it but it’s possible there were some from the front or back missing since I received the book used.
There’s two stories I remember.
One was about a girl who became obsessed with bubble gum trying to blow the biggest bubble ever and she blew one as big as herself and it popped and she got covered in gum.
The other one was about a boy who wished he was invisible so he could sneak out of the house and join the circus.
