"A. Montoya" Painting

Hello,

Trying to determine the value of this painting. It's one of two I found. Thank you.

 

The only A. Montoyas I found have much, much different styles. There are a few on eBay that miiiiight be by the same hand, but the signatures are drastically different. I did find out that the authentication company Royal Arts, Ltd. has been out of business for a long time, so no research help there. A bigger photo of front and back would be very helpful. That's all I could find.

EDIT
Well, the two signatures on your two are a bit different from each other... maybe you'd like a look at the eBay auction.

Even though they come with a certificate of authenticity, this is factory art..... Authentic factory art!

 

I was worried that THAT was the case...
