Things Found in Books
Abebooks not only sells books but writes about them every now and again. Today's essay is on Things Found in Books.
I've found a fair number of holy cards, some memorial cards, a few ordination cards, assorted advertisements and business cards, and in one volume years ago a service card for a Te Deum sung in St Patrick's Cathedral in New York celebrating the end of World War II. Alas, no money and no Mickey Mantle 1952 rookie cards in mint - or any other - condition.
