Some artists get all the fame, glory and prices for their original art (i.e. Adams, Miller, Ditko, Kirby, Wrightson, McFarlane, Lee, Smith, Byrne, etc.)
Others work away year after year, producing great art, but are (relatively) unappeciated and underrated.
Who do you think are some of the most talented yet under appreciated artists since the Marvel era began in 1961?
A few of my favorites that come to mind (ignore the bad spelling):
Bill Sienkevitz
Jim Aparo
Dave Cockrum
John Romita Jr.
Marshall Rogers
Dave Sim
George Perez
Klaus Janson
Steven Bissette
John Totelbaum
Curt Swan
Brian Boland
Norm Breyfogle
Neil Gaiman
Jose Garcia-Lopez
Jim Starlin
So who is on your list as being under rated and deserving of more historical acclaim that they currently get?
