Thrift Find Today - Aristodimos Kaldis painting!

Hello everyone,
I wanted to show you a painting I found at a thrift store today. When I first saw it I al.most passed it by; I thought it was a child's painting some proud parent had has framed!
But when I saw the From the Estate of Aristodimos Kaldis stamp on the back & looked the name up - I was pleasantly surprised!
2 questions please - it feels like it was done on board, but you can see the course canvas material - looks almost like burlap? - stapled to frame?
Also, where the wire you'd use to hang it on a wall was placed on the back of the painting makes it seem it would hang upside down from it's placement. Also the stamp appears to have been put on the painting upside down?
Do these raise any concern on its authenticity? Do you believe it's real?
After a few weeks without much art at my regular thrift store - this was a pleasent surprise!
I hope you like it (im still not sure what I think of it!)

 

I think this is the name of the painting?

 

Yes, Aegean Village. Not a palette one typically associates with the Aegean.

I like Naive and Outsider art but honestly that really does look like a kindergartner's work .

 

J'Man- Had a feeling you just might show up today with a bit of Art. Looks like Mr. Kaldi was inspired by Kandinsky.
Good listed find J-congrats ! Look,Elaine de Kooning even did a portrait of him.
