The Dublin plant, in Texas, ceased production of making it's Dublin Dr. Pepper, with imperial cane sugar, in January of 2012, after 120 years of production. Obviously they made enough to ship out for the next few years, and I came across this 24 pack while I was a worker at a local renown soda store called Pops, off of Route 66 in Arcadia Oklahoma.  

This 24 pack of Dublin Dr. Pepper has never been open by me. I have taken great care of it, for any collectors out there that want to get their hands on it. The value of this product as a collector will only go up in the years to come.
