Stamp Mysteries Solved - Post Your Mystery Stamps Here!

That is very interesting rockinrobin! Thanks for posting it!
A learning process for a lot of us.

@rockinrobin's stamp:
Just a hypothesis, but could it be that the stamp was pasted face down (which could explain why there is no design on it)? Later, it was removed from the original envelope and pasted elsewhere (maybe an album) (which could explain why the cancel is visible only on the stamp and not the envelope).

A difficult scan, but I'm not sure about a plateproof... it wouldn't be cancelled. It may be cut close. Check a Scoyy U.S. Specialised catalogue, early U.S. stamps were cancelled with various coloured ink and some carry a premium for certain colours.

Gussyboy1, I know I need to learn alot, since I've been out of it 20+ years.
Amit, one of the "stamp" corners is coming up, so I checked carefully under it and there is no print on the other side. I had not thought about checking the other side-thanks!
David, there is no color at all on the stamp, just a perforated piece of paper.Bobgggg identified the cancel, it comes from the Czech Republic. Guess I will look around some more. Thanks for your help guys!

Rockinrobin...It appears to be a piece of the
extra paper called slevage (sp?) that would surround a sheet of stamps after they are perfed. The actual stamp that was attached at sometime may have fallen off or been removed, leaving just the piece you have.

The stamp was probably to the left of your item as the
cancel does not hit the envelope paper on that side.

SF...Just saw your question re peroxide. A small
amount, say a tablespoon to a cup of water should
be enough to reverse the process on the orange
stamps.

meostamps, I thought that selvage(not sure of spelling either) was not perforated on all sides??? This "stamp" (or whatever it is) is perforated on all sides. So could this still be selvage??

Rather than be from the edge, it can be from
the middle of a sheet. See the "spacers" in this
sheet from Israel. Maybe the same type of use, just
does not have a design on it.

Good eyes Meo... Nice catch...In my opinion, Maybe someone used
one stamp from a "gutter pair"

So far a pretty interesting mystery. while one good theory is that it is a slevage and there are more than enough examples to support this one.

however the missing stamps or what appears to be missing stamps might hold the key to that theory.

I will propose another theory, chalk paper. This was a chalk surface paper used for printing stamps. Any attempt to remove the cancel on a used chalky stamp will also remove the design. In addition the immersion of these stamps in water will cause the design to lift off.

I would rule out chalky paper. The cancel would
have been on top of the stamp design and would
have also washed away along with the design. Also,I believe Bobgggg mentioned the cancel
being from a Czech city. Chalky paper issues are
usually associated with British issues.

Looks like I need to check through my Czech stamps (no pun intended)and see if there might be a match to the "stamp" I have. I doubt my grandfather had this one in water, since it is still on paper. There is nothing on the paper backing, so no help there. Thanks meo for straightening me up on gutter pairs, and thanks to the rest of you for helping in my learning process. Maybe I will try to get a better scan up when I get back home.

I thought of that but it is still possible that the ink stamp penetrated deeper. In any event it is a theory. Chalk was used in many of the eastern countries of Europe too. For example from the middle of the thirties Estonian stamps were printed on white chalk surfaced paper purchased from England.

What I'm having problems with is the year of the date stamp. The region that I think the post mark came from could be in fact Germany depending on the year of the date stamp.

The area is famous for their spas and is near the area where Marie Curie obtained her radiative material.

I looked up Radiumbad Brambach on google. The article I found said Radiumbad means "radium bath". People go to the spa there because of the "radons" in the water.. believe it has "healing" elements in it.
mkfarm- I can't make out all of the numerals in the date, so I don't know if I am missimg anything.I did see a reference to "Bad Brambach" in a german article,but the translation didn't make much sense. I need to try to find out more about which country first, I guess, before I try to find out more about the """stamp that may not be a stamp". Thanks to you all for your help!
