Many years ago someone in our office had the bright idea of giving away boxcutters emblazoned with the company logo
we "lost" them pretty quickly and resorted to ball point pens
!
Got this off Swissair in 1987 - the only time I ever flew first class with them (company I worked for wanted to get me back from Athens on a bank holiday, steerage class completely full!)
As for lapel pins, I spent many happy hours trading them at air shows and exhibitions - sad really!
