Tom Boblittabout either of those series but two on left are tin litho pinbacks and the other is from a HUGE set of pins. All three are tobacco inserts. An ebay Live auctioneer had a bunch of lots of tobacco pinbacks and had a huge lot of the blue ones. They have different sayings on blue red or green backgrounds. The ACC lists P4's with something similar and I think they may be P4's. I think the other two may be P21's. The ACC for P21's is as P3 (Mutt & Jeff) but tin (no celluloid ). SO......I'm going P21, P21, P4 from L to R in your photo. Not particularly valuable. $2-$5 generally will pick a clean one up. Baseball content might push them upwards of $10 though.........
