Chris--Looks like a good deal to me! Every time I see something like that on ebay, it brings right up in that money range and its usually just for the GULF letters. You've got a LOT of lettering there for the money. Use what you can and the rest is very sellable if theres too much.
Glad you were able to use that picture posting tutorial and get the pics up to share. It really helped me when I posted my first picture. How about a picture in the future when you get the lettering in place? We love to see what others do with their finds. Heres a picture of how I displayed my Cities Service lettering! Right above the old work bench! Enjoy and don't forget to get us a picture of the sign in place!
