Thanks for helping me try and figure out what the following stamps are.  When I get these stamps ID'ed I will post the answers so we can all know.

This interesting litle one came in a kiloware mix.  I am stumped.  Any ideas?
Well based on feedback received, it seems that this one is Belgian, now to see if there is a number to go with it.

It appears that these are Russian trade union membership stamps.  Many thanks to the members at Stamporama for helping me figure this out.

This one is no longer a mystery it is from Liechtenstein. Scott 39, Gibbons 35. Printed 1922 Perf 12½.

These have been identified thanks to some members of Stamporama.  They are Tannu Tuva Scott Numbers 2, 3 and 4. Printed by litho in 1926, perforated 13½.
