Here are the other countries. Including: Austria, Belgium, France, Italy, Mexico, Netherlands, New Zealand, Philippines, Switzerland, Hungary (Empire?) and one from Soviet Union -- which I think is probably a stray from a different box in my office. There is also one I think may be a Tsarist Russia?
At the end are a couple of curiosities - four stamps that I think might be from pre-Revolutionary Russia and an Approval Sheet of numerous countries. I recognize: Belgium again, Poland, Czechoslovakia, Eire, Norway. There is a Republic of China - is that Taiwan? The top right could be pre-Revolution Russia again?
I would be grateful if someone can confirm if these 6 stamps are from Russia, and of what era? Also if anyone can identify the second row, third space (pale tan stamp), second row final stamp (light orange-brown), and the two purples on the next row: "Travancore Anchel"?
Thanks again for any information about any of this.
