Cutlery. It's got to be. My cutlery draw is entirely full of the stuff, if it ain't got a logo it's out. Some of my friends have also stolen some for me, or got it by other means. Cubana, MEA, Finnair, SIA, Thai, JAL, Qantas, RAF, Pan Am, BEA, BOAC, Delta (from the 60s), KLM (from the 70s) etc etc. I have two boxes of Pan Am napkins, half a dozen Olympic [tray] tablecloths, half a dozen Cubana napkin rings, four Pan Am water glasses, four Pan Am shot glasses, four Eastern AL sherry glasses, tonnes of other cool stuff and my fave, a 1960s Pan Am stainless steel jug with the logo engraved. All I know is that it's been on a lot of 707s and probably served a lot of very famous people. What I want now is a catering trolley, preferably with a flight attendent attached. That's probably the ultimate souveneir.
