Hi Gaspare, your question was answered on 4/19 in Bill's imperial art thread...wish I had an ideal and affordable method of display but don't. I know you being a comic art/comic guy, you're aware of mylar and archival-grade storage methods. Ideally it would be nice imo if put in period to the time album. Maybe a frame for the one's that are special to you. Good luck and I would be interested to know if you find a great solution.
Posting this unusual one that looks somewhat home-made having a thin protective cover and writing on the reverse. If anyone can translate (if worthy or not a problem) that would be great. Thanks
