I had a quick look and couldn't see this already mentioned anywhere else.
Tim Piltcher is running a kickstarter (http://www.kickstarter.com/projects/2016810024/comic-book-babylon-a-cautionary-tale-of-sex-drugs) for his "shocking, revealing and completely unofficial memoir of DC Comics' legendary London office, to celebrate Vertigo's 20th anniversary".
The kickstarter has already reached its £3,850 funding target, but if it reaches £5,500 in the next 11 days, then the three promotional badges will be upgraded to enamel on silver plated metal by Termight Replicas.
