So it wasn't quite 10' x 200', but it still was the largest single sign job that I have ever quoted and produced and it turned out beautiful. The sign ended up being 7't x 150' long, framed out with four horizontal rows of 1" aluminum tubing, qty of 36 4' x 7' black/orange Alumalite panels butted together with aluminum "H" channel.
The letters and graphics are all Oracal's 951 series vinyl and were applied in shop, three panels at a time. The orange alumalite panels were covered in the 951 with the help of Dale's "Big Squeegee"...Love that thing! I was going to have them painted in an automotive finish but the painters let me down at the last minute. All in all it took about 3.5 weeks from start to install!
It is the backside of the bleachers to the schools main field.
