Thing is if you'd have used a bit of logic first&formost you would ve saved
the penny's ie two 3mm thick perspex sheets drilled at 4 corners and cut to
size.
The Logo could have been printed out and laminated then sandwiched between
the two sheets of perspex and sign changed at any time during the course of
the buisness.

Sounds like a bit of a nightmare.
Firstly you would have eater ingress between perspex & laminated sheet.
secondly, 2 x 3mm perspex sheets would need a lot of fixing points and
would be too easy to crack, whereas Ply was just dripp through @ Screw.

I would have no hesitation recommending Plywood again.
Actaully better than our foamex experiences bot Acrylic rules if funds
allow.
