Slightly out of the ordinary for what I usually collect:
Penzler, Otto. Mysterious Obsession: Memoirs of a Compulsive Collector. The Mysterious Bookshop, 2019. First edition hardback, #219 of 250 signed, numbered copies, a Fine copy in a Fine dust jacket. Non-fiction. The story of how Penzler assembled his famed collection of mystery first editions. This edition sold out before publication. I have precisely one copy available through Lame Excuse Books. Bought directly through Mysterious Bookshop at a slight discount off the $50 cover price.
