First is 3” reading “Flash Gordon/Ming The Mercilous.” Art includes “Alex Raymond” facsimile signature at left. Top curl reads “Flash Gordon Series/#1” while bottom curl reads “©1974 By King Features.” For the following 3 buttons in the 3” size, our Tarzan consultant Robert R. Barrett provided the information that these are part of a set produced in 1973 by John Rose with the permission of Danton Burroughs. Two buttons are titled “Tarzan” with facsimile signature of H. Foster. Both yellow and white bkg. versions are here. These designs are unnumbered, but following these subsequent buttons featuring Tarzan art by various artists were numbered 3 through 6. Also included and produced by this same man is a 3” unnumbered button with “Tarzan” art by “Frank Frazetta.” While this button is not numbered, the creator considers it part of the set he produced. Also in this group is a 6” “Edgar Rice Burroughs Tarzan” with artist name “Hogarth.” This has curl text “©1974 by Edgar Rice Burrough Inc.” and “Tarzan Special – Number One.” Couple of tiny faint gray marks on the bkg. of the white bkg. 3” Tarzan. The other 4 are N. Mint and display Mint.
