Hi, I am currently working on a construction of used billboards. (2mm polyester 6 mm Styrofoam 2mm polyester).

You take a used billboard ( I did get mine for free from a advertising company when they were changing a big Supermarket’s house style).

A aluminum L profile and some locks and stuff.

Total amount of money spend around USD 75,00

Low cost, light weight end product.

As soon as it’s ready I will post a picture on the forum.
