I've been going through my collection of older advertising chips to see if I can find the where, when, and why for their use. You saw the movie-related chip that, with help from fellow collectors, I was able to determine was made for the Deep Rising film in 1998.

Today I'm showing a chip used at a professional Convention held in Las Vegas in 1971. This was apparently a hand-out advertising the product of a Company called Convertors. I've submitted this to TheChipGuide with this information:

Convertors, adv chip handed out at the 1971 Association of
periOperative Registered Nurses convention in Las Vegas, Feb. 8-12, 1971. Convertors appears to be the name of a division of a company that supplies flexible surgical supplies like surgical-drapes, gowns, and even marking pens to outline the part of the patient involved in surgery. Beige, H&C mold, LCV variety, hot-stamped in blue, dated on one side.

The company today appears to be the Kellan, Inc. Medical Equipment Division in Arizona.
