3.5”x5.5” card with nice illustration on front which is same illustration used as book dust jacket originally published by McClurg in 1917. Reverse has text that reads “A New Tarzan Story by Edgar Rice Burroughs.” Also notes that book is illustrated by J. Allen St. John. Postcard was sent in to obtain a copy “The Son of Tarzan.” Card is unmarked and not postmarked. Some very minor corner bumps and a very faint crease in upper half across letter “T”. This crease is not noticeable except in reflected light. Exc. First we’ve seen.
