Geez. There are some nice ones in there! Your friend might consider investing in a few nice display cases. I’d be worried about them getting chipped by hitting against each other.
Working on new space now I have out grew frames. I don’t have space to store any more so they have been sitting here and there for past 6 months or so. I had a plan in place and in process the wife just did not know it. There is this room that is never used has china cabinets 12 foot long and 4 feet tall on 3 walls. Going to back light the ones you see through in upper part. Put all frames In cabinets below with fold up tables from lower cabinets to allow access to frames
You’ve got a lot of nice artifacts and your display idea rocks... pun intended. Is the brown one in the upper left corner in photo 4 a Hardaway? The drill in the upper left of photo 6 is awesome.
