I did not remove this from the frame. Not sure if there is any signature. It appears to be oil painting and looks to be painted directly on a board.
There is a lot of paint chipping and staining from exposure and no glass covering. The frame has surface cracking throughout and some areas where gesso has broken off and you can see the wood underneath.
This will need some restoration/repairs. Interior frame is 34.25" x 23". Pictures should give good idea of overall condition. Often, you only see the first one selected and depending on where you live, it may not be the cheapest one. Please look at costs for both of them (I hear this can sometimes be hard to find).You can ask us for a quote.
