Large painting signed Phillips by Samuel George Phillips? Pastel?

I found this large (43.5 x 28.5 w/frame) painting at my favorite thrift store today.
I almost passed it by because I thought it was a print, but someone else said it was a pastel & since it was 75% off the $39.95 after coming from another thrift store owned by the same family (they rotate stuff that hasn't sold), I ended up buying it for only $10.
2 questions - would they put a pastel behind glass?
Looking up the name Phillips , an artist called Samuel George Phillips came up whose works have sold in the $1,000's!
I looked at a couple of his signatures & while most were his full name or S. & his name, I did notice the letter P of Phillips looks similiar to mine?
Could this piece be by Samuel George Phillips? And a painting? (Close up of tree & house I hope will help you)
Thank you & have a great weekend!

 

Yes, very easy to smear/smudge otherwise. Think there's more disagreement about whether to put oil behind glass.

 

Well that's good news #1 ! Now fingers crossed that it is by Samuel George Phillips!
Thanks!

 

PS - I looked up Samuel George Phillips pastel after Bronwen told me pastels were kept behind glass so they wouldn't get smudged - and found this example attributed to Samuel George Phillips that was signed with only his last name like mine! (the others I found were either spelled out or had the Samuel as a initial)
Are there other examples where he only signed his last name?
Thanks

Pastel, watercolor and colored pencil are usually behind glass. That's why my paintings are so expensive for what they are. The cost of framing with glass is outrageous.

 

Yes, but its funny because his pastels go for a few hundred, but his oil paintings go for thousands & 10's of thousands!
I wonder why?
