Terrible condition block that came with a nice group mix of early revenues a few years ago. I was not impressed with this stamp, first thought toss it into the box to ship to the VA Hospital. But then got to looking at the cancel dates. Four different dates 10 July, 11 July, 12 July, and 13 July 1915.
So now it has a place in my stock book, and soon will be making a frame for it to sit on my desk, in its right and proper place. More of a remainder to always examine every stamp!
Do other members have similar examples on revenue stamps? Would like to see others.
