As I'm slowly getting better at ID-ing stamps from scans, I'm steadily getting more and more annoyed at mis-identified stamps on
ebay (at least when it doesn't work out in my favor). Tonight I found this described as a 33:

It's a 35! At the very least, w/o three pearls on the outside, it's no 33. Aggh!
Should I tell the seller? I don't want to come off like an ass, but somebody might pay way to much for this.
