I’m in the museum sector.
Never pick something up to move it until you’ve seen the place where you’re moving the thing and it’s clear of junk.
It’s safer to make two trips instead of one. It’s safer to make three trips instead of two.
The best thing you can do for something old that looks like it’s slowly falling apart is usually to leave it alone.
I’m a museum curator based in Europe (very different from the Americas). It’s a wonderful job of travel, being close to history and bringing some goodness into the world, if you don’t mind the salary of working for a charity.
