Marvel Sketches - Complete Avengers, 70th Anniversary and Fleer Retro

Hi all

I'm always looking for Captain America and Scarlet Witch sketches from the Marvel 70th Anniversary set.

Also any Scarlet Witch sketches from the 2006 Complete Avengers set and any Storm and Silver Surfer sketches from the Marvel Fleer Retro set.

I am chasing particular artists but will consider all.

Cheers
John
