Found a nice painting w/small hole - worth saving? Artist's name?

Good morning everyone!
I did my estate sale yesterday and just 1 customer made UT a great day - he spent almost $1,500 and bought my Alexander Calder & 2 Roy Lichtenstein prints, as well as some guitars and other stuff.
When I was bring the prints to the front where we were adding everything up, I saw this painting in the stack that the Calder was the first of.
I saw a small hole & don't know if it happened right then or before - I didn't remember the painting.
It's not signed on the front but it is signed on the back of the canvas.
Can anyone tell who the artist is?
Do you think it is worth having repaired of just sell cheap/give away to someone who buys more art from me (estate sale today too!)?

Thank you for any help & have a great Sunday!

 

Sell as-is. Painting is formulaic but may be a real artist. I see a lot similar attributed to Horst Baumgart. I am not convinced that these are not factory paintings.

 

Thanks verybrad!

 

Seems that Horst Baumgart is/was a real person. I am finding some works with authentication and metal gallery tags on the front. Those are likely real. Yours.... I am not so sure about, though there is not too much difference in the quality of the art. He may have just been a factory in and of himself.

 

"Supplies his works exclusively to..." Given the English-language write-up and the German source, suspect gallery sold to American soldiers stationed in Germany. Decorative art. Sell as is.
