These shirts are indeed manufactured by Freeze (RN# 71868). There are four newly discovered titles: Slam Jim, Camal, Real Garbage Candy, and Slacker Jack (gray). I bought them from a close-out dealer. The copyright on the shirt is 2010 but they were never sold in retail stores. The quality of the material is not that great...the brown Slacker Jack and gray Crust are slightly better (also by Freeze). There is also a black Slacker Jack shirt out there somewhere but I haven't found it yet. It would seem that even though these shirts were made this year, Freeze never found a decent retail buyer that wanted to sell them.
The sizes run a bit larger than both 10again and Top Heavy. I'm 5'11/175 pounds and size medium fits me just fine (although the sleeves are a bit too baggy). They will shrink after washing. When Camal was removed from the dryer, the beige color was spotty and uneven which pissed me off to no end. It will go in my pile of racquetball/yardwork shirts and will not be worn at formal events like weddings and funerals.
