Hello everyone! I have been gifted this antique but HUGE 120cm x 190cm (without frame) oil painting of old english ships fighting in the sea. Its a common but quite desired theme, and this one is gorgeous, detailed, very well made, the photos alone doesn't make it justice. Unfortunately It was stored rolled on, without much proper care, as it was removed from the original frame, but the canvas is not cut, doesn't have any holes or rips. What needs to be restored are a bunch of small white spots with paint loss, and a removal and reapply of varnish, as well as reframing.
On the back it has this signature that reads Stochausen .54, I could not find anything about this artist, but it looks european, and I dont know if it is from 1954 or 1854.
One guy is super interested in acquiring it for $600, but I have my doubts if the painting is maybe worth much more than that. Can anyone help me with that? Thank you all!
Here are the photos I have taken of the Painting, plus signature.
