seeking info about this very old painting. no artist. possibly from 1800's i was driving through my neighborhood and saw a guy cleaning out a very old house and this was leaning up against the garbage can near the street. i stopped and asked if i could take it. he said i could have the painting but had no information to go along with it. my brother who is a vintage expert says it is possibly from the 1800's. there is no artist signature or anything written or stamped on the back. also this is the frame that came with it. unknown if it is the original frame.
