I honestly have absolutely no enthusiasm for the current generation of comics writers and artists, but here's a modern contribution to the type of artist jam issues I started this topic to discuss, and a cross section of writers and artists currently working for DC.
The highlights for me are the Mike Grell story, and the concluding tribute to the recently departed Dennis O'Neil, written by his son.
