Don't Put Them in the Dishwasher

Here are four glasses dated 1976, which I bought at the time as released. I think from Dairy Queen, here in OKC???

Here is the promo poster in situ in the Comics Closet of the Fortress of Markitude.

A little more detail in CUs of top and bottom halves.

And a CU of the corner.

Finally, here are those glasses on one of the shelves in the Fortress.

PS this person's post shows the backside of the glasses and transcribes the text from same.

You must admit, many might have the glasses, but who has the poster????  See you Monday, campers!
