Arshile Gorky painting + Armanian memorial plaque 1918?

These are 2 more Armanian pieces i found at my local thrift store (along with the 4 paintings by Armand? I posted about earlier) - I guess a Armanian home did a spring cleaning and donated a lot of stuff?

I am pretty sure the tiger painting signed A. Gorky is by Arshile Gorky?

The memorial plaque is dated 1918, but an image search turns up many exactly the same?
Some say art deco, so.e say colonial - what is it (and why so many exactly the same?) & how old is it really?
Thank you!
