Vintage Alexander & Wilson What's Yours? Drink Marker Set

Found this cool vintage "What's Yours?" drink marker set from the 50s or 60s. It's a full kit with different colored plastic clips that go on the rim of the glass so you dont forget who ordered what. Has labels for stuff like Scotch on Rocks, Bourbon & Coke, and Soda. The case has all the instructions on the inside lid. Really neat piece of mid-century barware for your next party or just to display. Case has some light wear but everything looks pretty good for its age.
