Here’s what I’m looking for:
Old children’s book
Mostly line drawings
The line drawing might have one splash of color in it on some pages
Very few words on each page, maybe one or two
About a little kid, has a blanket in the story, maybe the beach?
Has a humorous ending
Small book, I think hardback
Horizontal, rectangle
Yellow cover maybe
Read to children in the early 1980s so may be published 1968 to 1984?
