I bought an older home which was occupied by the same married couple from the time it was built (late 1930s) until 2009 at which time the widow died, the husband having died back in the 1970s. There were a few items left here in the house and these mugs were part of the lot. I do know the husband had been in WWII and later was a pharmacist. I do not know if either had gone to Princeton or Yale as their families were from South Carolina and that is where they lived here in the house. Any info as to circa or worth would be greatly appreciated.
