Joining two pieces of plexi without ....

[Janis]

A customer would like me to place an old poster that's falling apart between two pieces of plexi but without a frame. My brain is dead at this moment and I'm not coming up with a good plan for doing this and a way in which it could be hung. Any suggestions?

If the poster is falling apart, it is not going
to stand up to the rigors that this sort of display inflicts. Neither would it do well in the
light. Your brain is fine, the request in not.
