GB Banker's Box Labelling Ideas?
So this is a bit of a weird thing to ask for help with. This Halloween I'll be putting together a Ghostbusters "recruitment orientation" display for my local town's trick or treat. I've made several other props and bought quite a surplus of laboratory like/industrial furniture.
The shtick is basically a low-employed, forgotten Ghostbusters Division seeking help. I need to fill a shelf with various interesting props, but it's pretty large and I don't have much left.
A school nearby was unloading these boxes for free and I had a moment of inspiration. I need to give these guys various tags and labels, and probably make a few drip slime.
Anybody got some ideas for what I could put? I've got a few but not enough to label every box. Thanks in advance!
