Junior Billboards 12 x 6 What is best way to build one

Hey I would like to build a Junior billboard. What is the best way to build one out of metal. Does anybody have any plans?

You are best off just finding a used 8-sheet sitting in some sign fabricator’s yard. You can also buy them in kit form from Keeler Iron Works, and other steel fabricators.
