This is kind of an odd piece. I found it in the same place as that unfinished pencil piece by Kevin Eastman (BftP #166), and for the life of me I cannot remember what I did this drawing for.
Obviously, it features two of the main characters from TMNT Volume 1 #8 -- Savanti Romero (looking somewhat different from how he appeared in the comic) and Renet -- but why did I draw it? The layout of the drawing makes me think this might have been intended either for an ad or a pin-up.
I guess, like Savanti Romero himself, the true origins of this piece are lost in the dim mists of time. -- PL
