Not much ambiguity here. It's a clean, right angle, right facing dihedral, into a roof, which you pass with the handcrack on the right.
There is (or was, as of January 1, 2003) a loose block a few feet up in the crack. You can choose to either crank on it, thereby changing the lower section of the climb and possibly injuring your belayer, or carefully avoid it, thereby leaving the climb intact. I recommend the latter. :)
There's a downclimb to climber's left.
Protection
This corner pretty much soaks up gear; you can sink as much of a standard rack into it as you want, but won't need anything particularly large (up to a #2 Camalot is fine) or small (leave the micros behind.) Save a handful of pieces for the anchor on top.
This beta photo is not of Classic Crack but rather of another route to the left called False Classic Corner (aka The Case Of The Missing Nolina) (5.6)*. This climb pictured is a left-facing corner/ramp while Classic Corner is right-facing and steeper. The Leatherhead Arete (5.11a)** climbs the obvious arete between the two routes.
Is anyone familiar with the unnamed (?) climb to the right of Classic Corner in the Atlantis area? It is also a dihedral climb with a good-looking crack & looks a bit steeper than Classic Corner. It is formed by the same large block that juts out to form the right side of CC.
Has it been named since Vogel's last book? Does anyone know its rating? -wingerhp
The route shown in the photo is NOT Classic Corner. The corner to the right (right facing) IS Classic Corner.The route shown is appropriately named: False Classic Corner 5.6.

Better than The Case of the Missing Nolina, but pretty short nonetheless (about 30').
