Just note that the book I’m searching for is definitely not “A Birthday for Frances”.
My sister and I first saw this book in our elementary school back in the mid 70’s in the midwest of Canada. It was probably an American book perhaps from the 50’s or 60’s.
It was a smallish hard back book. The most prominent aspect was that it was made up of 3 colors, black, pink (my sister thinks it was bright magenta) and white.
The premise of the book seemed to revolve around a black and white animal family (skunks?) and a birthday cake with pink candles. My sister seems to remember that the drawings were very simple using black heavy lines. One of my recollections is that the end pages had vertical black and pink stripes.
Can you help us? We are so desperate to find this book again!!
