WCE 1893-Large Catalog/Book from the Entomology Department at the WCE
I assume that not too many collectors care a great deal about the thousands of inscets displayed at the fair, but this is a very rare (I’ve never seen one before) catalog of that exhibit. The cover is quite tattered but the guts are in excellent condition; there is no back cover. Inside is information on every exhibit, including a variety of details, such that a half dozen decriptions fit per page and this is a book-length document.
Granted, it's not the most exciting book we are offering but if you collect Columbian books I can guarantee it might be years before you could locate another, if ever. I'm sure it was printed in very small quantity and there wasn't a rush by libraries around the country to acquire a copy.
