A couple of days ago, I was browsing revenues at the APS Stamp Store and saw the accompanying listing, which purports to be a pair of R63e. The price was minimal, but it seemed clear to me that this was not an ultramarine revenue. Therefore, I sent a note that I thought the stamps were misidentified.
This was the response I got: "We have a complete collection of early revenue stamps in the Reference Collection. This is a very different shade from all of the other blues, so we're going to let it stand."
Am I crazy to believe that this is not an R63e pair?
