I recently swung by Kayo Books during a trip to San Fran. What a fantastic place. Most vintage book stores have only a small section dedicated to the crime, noir and sleaze paperbacks we love. Kayo is all pulp all the time. Thousands of vintage paperbacks, magazines and other cool stuff to browse through. Such a pleasure to shop for vintage books in a real store instead on the accursed flea bay. I can only say that if you find yourself in S.F. and you love vintage paperbacks you must make a stop and do prayer at Kayo.
I was able to pick up some good stuff, including some lesser known Spillane novels.
