The picture shows a view of this Old Swiss Air Airlines Advertising Stick Pin. The pin is not dated but it is old. The metal may be either brass or gold filled. On the end of the pin there is an airplane. It is not discolored as the picture suggests. It has a shiny gold reflective surface. Part of the wording on the back is obscured by the pin being attached. What can be read on the two sides is as follows:
SWISSAIR (logo)
HUGOENIN ???? LE LOCLE
The advertising stickpin measures 2-1/8'' long. It is in near mint condition.
