A set of Fourth Bureau Issue die proofs identified as being "mounted on very thin card" appeared in a Siegel Auction, Sale 389, February 9, 1971, that featured the Rudolph Wunderlich collection of essays and proofs. They were unsigned and without control numbers since their size was given as 3 x 3.5 inches (76 x 89 mm), about the size of a die sinkage.
I have searched for considerable time but have found no clues related to their existence. Is anyone aware of the set or possible individual dies of the set?
I am compiling data on Fourth Bureau Issue proofs and would like to bring my data up to date for the Wunderlich proofs.
Quote: Many of the proofs still exist, although some of their proof cards are trimmed down from the normal 6 in. x 8 in. format. This frequently removed the control number on the reverse of the card.
