Very rare solid plastic tap knob with “Stegmaier” engraved in the back side. I’m not positive of vintage, but I believe this may be from the 40’s.
On the top is a typical wooden case from the 30’s and 40’s. On the bottom is a wood and metal picnic cooler from the 50’s and 60’s. The cooler is complete with cooling coils and still functional. The faucet is on the unmarked, front side.
A Taylor-Merchant slide viewer and Stegmaier slide. Advertising suggests early 50’s vintage. I believe these were used by salesmen for presenting all types of advertising samples. I Wonder how many of these  Steg slides survived? I know of one other.
