Book Trade Gems

Anyone who handles old books will have come across these small and sometimes beautiful labels pasted discreetly (more or less) into the endpapers. Booksellers, binders, printers, publishers, importers, and distributors of books used to advertise in this way their part in bringing the book to market.
Seven Roads' Gallery of Book Trade Labels began with labels found in their own books, but now it is mainly a virtual collection -- each entry is digitally scanned from books found in the excellent research library.
