Quoted from goatdan:His is most definitely original. I bought some from the same source as he did, and when I bought mine they included a full sheet of the yellow caution bar stickers in case I wanted to affix them to the two sheets of glass that I got.
Thinking back on it a bit more. I picked mine up at the TPF. When I got there Rob was not there but someone else was handing out the glass on his behalf. I asked about the yellow caution bar, and he said that he didn't have any. I didn't press the issue further because I was happy to get an NOS glass at a reasonable price. Rob may actually have those stickers and perhaps sends them when he mails a sheet, but that was my experience.
Now, getting the purple crap off the glass was a whole other fun project that I wasn't expecting, but I love the end result.
