Purchased from end-of run overstock many years ago; an unread copy. Published by The Essay-Proof Society, The Essay-Proof Journal was the premier periodical for English-language information on worldwide proofs, specimens, essays, and banknotes; though certainly weighted towards US issues. Excellent illustrated articles throughout it's run. This includes whole # issues: 166, 136, 129, 175, 14, 171 (Trans-Mississippi),, 138, 160, 165, 176.
