My father bought this oil painting back in the 70's for around $400. It's been hanging over the fireplace the whole time and recently he decided he was going to get rid of it. So I told him I would take it. My mother has seen lithographs of the same image only a lot smaller. The painting is 24" x 48" and is in excellent condition. The signature seems to be Werner Hoppman but the last name blends into the background and it's hard to make out and I haven't been able to find info on such a person with the same name. Can anyone tell me any info on it?
Thanks
Bob
