I'm trying to track down the mystery of the missing color Bat sketches from OS3. For some of the OS3 characters, some of the artists drew two color sketches of the same character. But for Bat there seem to be some real gaps. Here's what I've been able to identify as having turned up for the various artists, with respect to color Bat sketches:
Engstrom - 2 (I believe this is all of them)
Walton - 1
Griffith - 1
BHOB - 1
Simko - 1
Wheaton - 1 (I believe he only did 1)
Zeleznik - 1
Kirscht - 0
Camera - 0
Smokin' Joe - 0
Zapata - 0 (but he did no color sketches for OS3)
Any insights as to the whereabouts of the "missing" ones - particularly Kirscht, Camera, and Smokin' Joe?
