It's here, the new 2010 Ashkelon dig shirt! 
Seen in the image is a decorated brazier fragment from the 2nd century BCE found during excavation in Grid 51. In the 2nd century cooking was often done by putting a metal stand over a fire. The decorated fragment of the brazier seen on the t-shirt would have been an insulater between the metal stand and the pot in which food would be cooking. We have good parallels for this from the site of Tel Dor.
