I have several photos and my problem is actually keeping the autograph on the photo. I have several in silver and a new one in bronze, because the photos were dark and the sharpie markers showed up nicely on the photos. However, the autograph will rub right off the picture if it is touched or anything. I can't store it because it will rub off inside whatever case I put it in, and eventually I will lose the autograph. Is there any way to actually keep the silver and bronze on these pictures? Heat? blow dryer? Or something along those lines? I guess for future use (although what I sent through the mail I can't control what they use) I try and avoid darker photos, but for the ones I have, is there any recommendations? Thanks....Bob
