Yeah, what the hell has Bart Sears done since the 90s? Like he fell off the face of the earth.
I think the sad reality is those big two didn't want to pay the "superstars" the page rates their worth, and these guys make far far more going out to conventions and doing a single commission than they would for a labor intensive book with interiors.
Not to open that can of worms but that's why Marvel and DC books are written and drawn by people that just plain can't write and draw, and all the remaining living legends in the industry just go town to town and make mad money on commissions and variant covers.
Eh....it was it is I guess. Sears' stuf on C.O.P.S. was sooooo freaking good. Not that man can DRAW!!
