Lot of 3 Pan American Airlines 1950s Match Books

This lot of 3 vintage matchbooks are souvenirs of the defunct Pan American Airlines. These are circa 1957-1958...one of the backs has a pocket calendar for those years. One matchbook advertises the CLIPPER CARGO service. The other 2 show artistic illustrations for destinations...New Zealand and Tahiti. The matches are gone but the matchbooks are in excellent condition.
