Featured 1970's-80's Farm Landscape Etchings

I purchased these etchings at a thrift store in Three Rivers, Michigan last week. I would like some help figuring out who the artists is. I am guessing that they date to the 1970's-80's. The frames appear to be walnut and are nailed at the corners. The plate size is about 16" by 7". The backs are identical and have no labels or information. The scene seems typical Midwest to me, so the artist might be from Indiana, Michigan, Illinois or Ohio. The best guess that I can come up with for the signature is something like Spence or Spruance? Thanks in advance for your help.

 

Love these. I see Steward, but didn't come up with anything but J Stewart.

 

Can't help, but wanted to say, very nice
