Let me preface this by saying that I know this in very poor shape. The stamp was found with some other older stamps and they appeared to have been cut off of the envelopes, hence the back of it.
I have been on the site online (theswedishtiger site) to try to identify it, but I'm just having a difficult time as the black postmark is covering some areas and frankly, I'm getting very, very confused. Any help will be greatly appreciated!!
