I have a large E.Johnson painting. The OldStagecoach. I have had it for over 25 years. Its has a wooden frame paper backing and is signed on the bottom. Were all reproductions also signed.

He was a co-founder of the Metropolitan Museum of Art in NYC and has his name inscribe in the entrance.

He died in 1906, so reproductions would not be signed.

The original size is 60.24 x 36.22.
Modern reproductions of it should run about $350-500. Depending on the quality of work, whether is is an oil reproduction vs. lithograph, yours could be valued close to that because it is framed.
