Help with possible origin

Thank You Yuanzhumin and Ariel,
I do feel it is from before the 30s for sure as it shows definate signs of age.
There is an oval with some letters, I think, on the other side but it is so faint that I cannot make it out. I have highlighted the oval with green dots and I think I see "RUSIN" if you look closely at the bottom of the oval.Maybe it is some kind of import mark or something
