I have this LEGO mosaic consisting out of 3 by 3 baseplates (32x32):
As it takes up too much space lying flat, I would like to mount it vertically or near vertically, slightly leaning backwards, like on an easel.
I'm looking for a solution that is modular, i.e. that I can easily take apart in smaller parts so I can put it in luggage for travelling and that is also as easy as possible to reassemble.
Also, I'd prefer a purist lego only solution, avoiding gluing if possible.
Any ideas?
