Margaret Bloy Graham's "The Plant Sitter"
Several pages here from the husband & wife team of Margaret Bloy Graham and Gene Zion's delightful The Plant Sitter, from 1959. I love Graham's drawings and wonder why she isn't more well-known today; I could find hardly any biographical info about her online. I also especially like her book Dear Garbage Man. At any rate, this one seems to be out-of-print and going for ridiculous prices, so if you like these images and want more, check your local library.
