No, the top tube was wrapped (albeit not very well), as was the rest of the bike. It wasn't a bad packing job, it also wasn't a great packing job--but I don't think I can fault the shop for under-packaging.

I think my biggest problem here is that I don't know who to trust. The damage could have occurred years ago, it could have happened at the shop while they were disassembling the bike, or it could have happened during shipping. My guess is that UPS has considered these possibilities as well and will decide in their own favor.
