as I stated on MoPo
the site does show the work of other artists as well as Kallis, probably because many people do not realize the 1sheet artist may not be the half sheet artist
in some cases there are 2 artists on a poster (Kallis/Brown, Kallis/Smith) when elements from one design are matched to another.
I hope to eventually be doing serious research on artists soon if I have time.. I hope
