Charlie Yup and pals

Detail from Flora’s third children’s book, Charlie Yup and His Snip-Snap Boys (1959). Charlie, who wields a mean scissors (his “Snip-Snap Boys” are paper cut-outs), is in the upper left astride Beezer, his “helicopter horse.”

For fans—like us—of Flora’s 1950s big-eyed figures, this was the end of the line, his last satisfying children’s book on an artistic level. He wrote and illustrated 14 more, which sold well and charmed generations of young readers. But our favorites remain the first three (Fabulous Firework Family, The Day the Cow Sneezed, and Charlie Yup), all produced during the 1950s. His next book, Leopold the See-Through Crumbpicker, published in 1961, showcased an entirely different style of character illustration.

Charlie Yup is the rarest of Flora’s books. It rarely turns up on Ebay or with antiquarian book dealers—and when it does, the price is lofty.
