Altec Voice of the Theatre Decal size and mounting location.

New to the site as member but have been researching vintage gear for a while here. Wondered if anyone knows the size and mounting location of Altec Voice of the Theatre decal on 828 plywood cabs from early 70s? Black, white and gold version. Have a pair that I have restored but the original decals were painted over and damaged. Seem to be a few places on ebay to pick up but they have different colours and sizes. Thanks for any help and greatly appreciate all the info available on the site. Awesome resource for diy and restoration!
