This book belonged to my aunt as a child, which dates it to the late 1940s, I guess. The author and illustrator was Peg Maltby (1899-1984).
They are quite large paperbacks, about the size of an old scrapbook or colouring book, and most of the pages are in black and white with some full-colour pages scattered throughout. The pages are brown with age, but still holding together well.
I guess my aunt thought perhaps it was a colouring book:
(Which reminds me that I once did this too in an old picture book at my Gran's house when I was staying there. Gran was horrified, and I was mortified. I really did think it was for colouring!)
Thanks for looking and check out more vintage goodies here.
