long story short, I have to empty my recently passed grandmothers apartment. while starting that process today after work, I came across this small glass. it's larger than a shot glass, but too small to be a drinking glass. my grandfather sold GMC rigs and trailmobile trailers, must be this was some sort of promotional gadget.
I put a paper towel in it to try to make the lettering show up better. I thought it was kinda cool.
