Thanks very much! Yes, the original seat tube decal was on the bike but so much of it was missing, I gave up and ordered new decals from the guy on eBay. I put on the seat tube decal this morning. The quality was excellent and the decal was identical in all respects, such as size, font, color, etc. It really took great care to avoid tearing the decal, but I got lucky and even was able to wrap it in the same direction as the original to overlap slightly on the backside of the seat tube.

This has gotten my courage up and I'll replace the downtube decals this week.
