Two Fish Out Of Water

via The Children's Picturebook Price Guide:
"As a child, I loved the story A Fish Out Of Water. It was, and remains, one of my favorite Beginner Books.

Written by Helen Palmer, the wife of Theodor Seuss Geisel, aka Dr. Seuss, A Fish Out Of Water has a ‘preposterous-ness’ one associates with a Dr. Seuss story. Then it’s not surprising to discover the story is virtually identical to Seuss’s Gustav The Goldfish, which was published a decade earlier in the June 1950 Redbook Magazine!"
