The picture is a good amateur attempt. Caveats exist: White water on the far side of the bridge is incorrectly represented. Some highlights are missing completely while some shadows are also missing. There is a comparative shadow group behind the two figures waiting for their coach. These are dark, strong shadows. I'm searching for others similar and am hard pressed to find them. The female's right arm appears to have the sleeve removed from elbow to shoulder-- not representative of the time period. The child is holding her hand, but he has one dark sleeve and ??one light almost white sleeve? Bad detail. Mountain atmosphere/clouds are not shabby-- that's a plus, but there are too many odd elements around to make this anything but amateurish. No signature? What's the back look like. I'll assume it's an oil painting, could be on board. Doesn't appear to be a mass produced scam-scale picture, but you must remain cautious. Until more info. is provided, I might would give you, maybe $50.00 for it as ambiguous as the thing is.
Good Luck
