Back to the future collage poster

Am attending London film and comic con in July and am hoping to get this signed by numerous stars. I would like it to incorporate all 3 films and include the characters and main props such as the deloraen, hoverboard etc.

After reading the general questions I've received. Here's some extra info:

1. Size = 12"x16" ideally
2. Characters needed Marty McFly, Doc Brown, Biff with gang, Needles, Mayor 'Goldie' Wilson, Lorraine Baines with George McFly (once as younger couple and once as older couple), Jennifer Parker, Marvin Barry, Principal Strickland, Clara Clayton,
3. Objects needed delorean, hover board, Doc Brown's tombstone, Einstein (the dog), the sports almanac.
4. Upto you if you print i or send me a hi res file copy so I can print in locally.
5. Portrait landscape your choice. whichever suits your style in fine with me.
