Featured Charles Surendorf, this is a woodblock, right?

I picked this up at my favorite thrift yesterday. Charles Frederick Surendorf 1906-1979.
My research leads me to think this is a Woodblock and not a later Linoleum engraving
The measurements are correct 13 3/4 x 5 3/4 approx.
Also the linoleum engravings are all numbered.
I think the frame is newer and was probably done to sell at the Looking glass gallery.
Any and all thoughts are helpful and welcomed.

Here's one from a museum's collection. Linocut according to description.

Hmmm. Now I'm confused. They could be wrong?

 

That looks like a lino cut to me.... is there something that makes you think wood block?

 

Only that the other ones I found described as linocut were numbered.

It just has the 'feel' of a linoleum block print. I do them myself, and the cuts, the solidity of the ink, and the lack of wood grain texture all seem, to me, to be a Lino-cut. I could be wrong, of course.

It's a very pleasant image.

 

Thank you very much @Potteryplease . Your expert opinion is greatly appreciated
