Behold ...!

THE BAT KNUCKLES

This alternate cover art by Philip Tan for Batman and Robin #5 was actually released a few weeks ago, but it was just when it was re-released today as part of the San Diego Comic-Con announcements that I noticed Batman's knuckle-dusters! Aaah ... it really is the little things that can make your day, ain't it?

Oh, and just in case you're inspired by Batman's example ... well, there are always these.
