Welcome to Oldgas!!
Hooked yourself up on one of those Sinclair plates with the goofy "R" did you??
What Dave, Mike & Mark said!!
And as Bob said, if Sinclair is your baby, the Wayne & Scott book is well worth the $30!! I dont even collect Sinclair and I love it!
Another great reference guide for signs for the guy with a big budget would be the Dan Mathews book, "The Fine Art of Collecting & Displaying Petroliana". Tons of sign info in there and it's only a couple years old. And if you dont have the budget for the big ticket item, the book is still great fun!!
Good luck!!
