I don't think newspaper wrappings will properly give you a date on them. People hoard newspaper.

That looks like a very logical frame. It looks like it is injection molded, which means one big squirt into a mold, and you have a frame. It would seem that it would lower costs.

OTOH you can hang stuff from the frame using carabiners!
ETA perhaps investment casting via foam blanks.
