I'm not sure if this is the right place to ask, and if it isn't I'd really appreciate being directed to the right place, because I can't find anywhere else! :)
Around 1965 my father got into art and did a large number of paintings, mainly coping artwork from books.
We recently found one of his paintings, a landscape, and he'd love to remember what it's a copy of.
Any ideas would be very appreciated. He's spent hours looking through books, and Google Images with no luck.
