Bryan Singer took to his twitter again to release a pair of images related to X-Men: Days Of Future Past with Michael Fassbender and an interesting pic of what appears to be some sort of mutant trophy case with items from X-Men: First Class.
The first image of Michael Fassbender, Singer adds:
Loving my monitors today. #MichaelFassbender #XMen #DaysOfFuturePast #Secondtolastdayofprincipalphotography
And with the second pic we see the coin Erik Lensherr used to kill Sebastian Shaw, Havok's costume, Sebastian Shaw/Magneto's helmet, and what appears to be a wing from Zoë Kravitz's character.
Included with that image, Singer added, "Artifacts."
Perhaps involving the future part of the movie somehow?
