Didn't realize these shop #15 CREB's were rare until I saw someone post one yesterday. I just bought a collection online and remembered that I had a shop #15 piece that was underpoured. I was mostly interested in this CREB just because of that, but once I remembered the shop number, I had to take a 2nd look.

Sure enough, this one has a 15 on the dome with no other numbers above or below it.

Pretty cool!!
