Roger- Thanks for the post. Do you scratch build your billboard stands?

Now these are cool! Thankyou!

From what I can tell, the largest standard size for a modern billboard is 14 x 48 ft. In HO scale that would be about 2.6" x 9" in 1:64 scale and 2.2" x 7.5" in 1:76 scale. Another standard billboard size is 10.5 x 36 ft which is 1.9" x 6.8" in 1:64 and 1.7" x 5.7" in 1:76 scale.

The 5.25" computer drive bay blanking plates are about 1.8" x 5.8" which is a pretty darn good approximation for the standard billboard sizes. The aspect ratio is nearly perfect.
