It's Mr Bones, cigarette-addicted DCU spy guy ...
... or maybe just a bit of symbolism in the coffee. All theories etc.
Len Wein is also the author, once again, of a back-up strip, less-related than usual to the main story. It's a heck of a lot of laughs, though, as Silver Age space heroes Adam Strange, Captain Comet, Space Ranger and Tommy Tomorrow face a horde of villains from Adam's past, including one brandishing a cosmic vacuum cleaner. It's a straightforward, light-hearted romp with a delightfully fluffy script. What lifts it above the realm of the thoroughly decent is the artwork of Walt Simonson, which is as dramatic, open and expressive as ever. His usual letterer, the great John Workman, also puts in appearance, and Allen Passalaqua is back to colour the adventures on other worlds.
Add in the simply spectacular Perez cover and you have a gorgeous comic which pleases by revelling in DC's complex history rather than being dragged down by it.
