Help with artist's signature on litho/print + there's writing in art background?

I found this at the thrift store yesterday & while trying to figure out the artist's name I noticed there is what looks like A. COMMENTED & under that RIVERS in the art just above the signature - what the heck is that?
Also - can anyone tell me who the artist is?
As always I appreciate your help!
PS - I also found a Tarkay print there that has Perry Art Gallery on the edge of the print - has anyone heard of it? (I found a Katherine Perry gallery online that has Tarkays - and it looks like a nice site; is mine from her gallery?)

 

First one is Menashe Kadishman

What you're seeing above that is most likely the watermark of the paper used by the artist.

 

Etsy sucks, but:

RIVERS, or RIVES?

 

Thank you both! I may still have test page (Miami Picker) but I only sold 1 item every month - or more! - So I just pay the higher fees on eBay but sell more (I recently sold a painting by a famous India woman for $4,500 and ended up with less than $4,000 after the fees) - (I had posted the painting here asking for info on it - but buyer asked me not to post her name again (I am guessing so he can resell it?) - the eBay fees are high but it's also largest market anywhere, right?)

 

Is the Tarkay by Perry Art Gallery a good piece or just a print (I've seen probably 100 Tarkay prints that aren't worth anything)?

 

Decorative print

 

i do very well on Etsy but I am selective about what I sell. newer items I sell on ebay.

 

My comment was more directed at the prices, and usual lack of great reference. I got lazy, didn't clarify, and just said they suck . So, I guess you could say, I suck. eBay is basically the same in my books, and I sell on eBay.

 

I never sold more than 1-2 items a month on etsy
