At Damyns, we can lock them (and anything else valuable) away overnight in a secure area.
Funny, people have said that should be done to me but no time limit was mentioned.
No, the real problem with security at any display is when the paying public are around. You need eyes in the back and sides of your head. Two issues, theft and accidental damage. Some of this stuff is coming up to be 100 years old and it’s delicate to say the least.
