Need help figuring out value for painting or whatever it is

[Digit]

My mother purchased this very large matted,signed painting at a yard sale back in the early 80's. She also purchased a bedroom set from the same people I have since sold which was very high quality. I had introduced my mom to yard sales late in her life and oh my god how she took to it! She would call me every weekend with her "finds" proud as can be. It was so cute! I had created a mini monster!

My mother is since deceased and now I have it. Yes, it is lovely, but I need to downsize and I believe it is too large for the space I am moving to. Framed, it is about 44"wide by 36" high.
Anyway, it is a huge framed and signed painting(?), watercolor(?) of a southwestern landscape at sunset signed by Gaylor or Taylor.

I can tell it is not an oil painting but I am a novice when it comes to art. How do I begin to determine a value and how can I tell if it is a watercolor or whatever?
Yard sales in my neighborhood yield people who want to pay 5$ or less for your entire lot.

Good grief I feel stupid.

1. Could it be 'Gaylord'. There's a water color artist of that name. See here for examples...

4. Finally able to post a picture

How would you price this? I would guess it should be a local sale as the glass would most likely break in shipping and it is pretty heavy.

Thank you for any help or suggestions.

Here is the signature "Taylor '76". The more I have examined this the more certain I am that it is Taylor and not Gaylor.

2. look at it with a 10x magnifier.

if the image is made up of dots, it is an offset reproduction. if there are dents in the paper along colorfield lines, it is a lithograph.
look at the tooth of the paper. a watercolor will use a paper with some texture. reproductions are smooth.

3. It was difficult to tell, but there is definitely texture to the paper

It almost seems like the paint was "dry-brushed" on in spots.

The other really obvious thing I had forgotten to mention is it has the date after the signature.
I am leaning more towards it saying "Taylor '76".

5. Hang on to it.

Right now, fine art is going for about 10 cents on the dollar.

You can always email a picture and describe it to a major auction house in NY. They are more than happy to tell you if is worth their time.

You'll need to take better pictures to send.

best of luck

6. Thank you for your sincere reply

It probably is not worth much, but somebody spent some money getting it matted and framed.

I would be truly shocked if it was worth more than $500, but now I know where I may get an answer!
