Made from 100% Cotton, this black t-shirt features the symbol adorned by the Reverse Flash, taken from the pages of the Flash-centric, alternate-reality comic book epic, Flashpoint!  In Flashpoint, everything Barry Allen (aka the Flash) once knew....is no more.  There is no Superman.  There is no Justice League.  There are, however, seriously skewed versions of Aquaman and Wonder Woman beating the @#$# out of each other and laying waste to civilization.  Oh, and a very...unexpected Batman. 

So...who or what is responsible for the creation of this damaged dimension?  Firstly, one should ask who has the ability to personally alter pre-existing timelines into near-apocalyptic ruin!??  Who benefits by altering dimensional properties if only the Flash can recognize this quantum dislocation!??? Why, the one person most likely to take pleasure in the Flash's confusion.  The Flash's opposite number, of course. The Flash's.....reverse.
