Lew Jaffe, a collector of bookplates and a blogger, recently posted this image of an original pen and ink illustration by Vachel Lindsay.
According to Mr. Jaffe, Lindsay's obit (didn't say which newspaper) reported that the Rev. Clark Walter Cummings officiated at Lindsay's funeral. The sketch is dated 1931, the year Lindsay died.
Along either edge of the page Lindsay wrote the words, "Fine books are immortal butterflies that sweep the skies."
No indication is given as to what book this drawing was made in, but it probably wasn't a Lindsay title.
