Following the reveal of the first few puzzle pieces yesterday, Marvel continues to ask the question "Who is Mosaic?" The new teaser, which Marvel has provided exclusively to CBR, drops another puzzle piece into the mix -- this one featuring Spider-Man. Three other faces can be seen as well, although they're not as easy to place as Spider-man's iconic mask.

The puzzle art comes from Stuart Immonen, although further details about "Mosaic" (is it a character, series, event, etc.?) remain unrevealed. CBR has also assembled all three puzzle pieces into a comprehensive image. Can you solve the puzzle yet?
