I've gotten a few autographs with incorrect inscriptions - intended to get them for friends but got them made out to me. Also have a few I just no longer want - trying to pare down the collection and downsize a bit since I have so much stuff - and would love to trade or just give away to a newbie looking to build their collection. I've tried magic eraser and Prismacolor blending pen, but neither have worked very well. Magic eraser leaves the photo sticky and the marker leaves some behind so it looks very faded but is still clearly there. Anyone have a reliable method?
