This page shows scans of my unmailed and untitled set of 20 b+w P.P.I.E. postcards. The outer slipcover/mailer of the set is in very bad shape, with end flaps missing, but the cards are in good condition. The front cover of the mailer is a glued-on Birdseye View postcard, matching a card in the set. The backs of the postcards are nearly identical, but not quite: 17 of the 20 cards credit "Pub. by Cardinell-Vincent Co., San Francisco", while the other 3 cards credit "Pacific Novelty Co. of San Francisco".
