Oil On Canvas Signed R. Lindstrom

This is an oil painting signed R. Lindstrom set in brown tones of some fishing boats.It is 12x16,16x20 with frame.  It has an artistic interiors paper on the back, certification ## 375861. also on a small piece of canvas attached to the back it reads "Ryan Williams 3-5-84 Nielson/80". 

I found a similar painting on ebay and compared the signatures, they were the same. Also the stokes and painting style were the same as well. The ebay painting is listed for $7,000.00, I hardly think mine is worth more than $100.00. Also listed with the painting on ebay was this information:...

The painting is signed R. Lindstrom. The artist Rikard Lindstrom is listed in Davenports 2007/2008 Art Reference & Price Guide & Hislop's International Price Guide to Fine Art. This Swedish artist was born in 1882 & died in 1943. He is known for painting Landscapes, Beaches, Harbors, Fjords, Boats, Fisherman & Ducks.

Is this the same artist from the early 1900`s? I am unsure and would love your help in figuring this out and finding what my painting is actually worth.
