Thank You You In Advanced. Please Help With Stamp Identification

Please can anyone tell me the year and to identify this stamp? Any links to it with historical details?

It is not a postage stamp.It looks like a cut out from a folder or sleeve for one of
A.Ilyin's maps.

Noting on here on anything in these links are close to this telegraph stamp.

Any clue on what it says and year? I do not see much in the links you gave to show anything that would help the issue. Nothing related to this question. But thank you any way. I remember years ago I found out it was a telegraph stamp. But forgot to record the details and since then have been searching.

It says "Cartographic Institute A. Ilina"
Yes I know it has the same shape as the telegraph stamps;but it's not one of those…
The black Russian double headed eagle emblem was used by many others in different sectors.
