I found this in a pile of junk at a estate sale this weekend. It is a coffee mug, about 3 1/2 " tall, and about 3 1/4 " wide. It is inked on the front, and marked 'VICTOR' on the bottom.

I am wondering if this was actually made by the same Victor Insulator Co, and if it is worth anything? Does any one out there have one of these??

Any help would be greatly appreciated.
