Remember when Sports Car Graphic magazine used to have a centerfold of art?
I saved some of those by doing decopage(sp?) on pieces of plywood. Didn't turn out as well as expected as I didn't know you were supposed to 'seal' the paper when doing it. These have been hanging in my garage since I moved in some 35 years ago.
I have one more that turned out a lot better but it's behind a bunch of stuff that's hanging from the rafters so I couldn't get a picture of it.
