Hello everyone! I received a stamp album from someone and I cannot seem to identify this stamp. It is a 3-Heller stamp from Austria, issued in 1908 with Franciscus Josephus I on the front. With all that info I think it should be easy to identify its number or something about it, but I haven't found a stamp exactly like it anywhere on the internet. Here is one from the same series I found: http://www.old-stamps.com/stamps/ka...st_3144.html
but it's not quite the same. Mine also has brown paper. Here are some images:
Thank you all!!
