Here's a small News (Not a rumor) about an interesting little prop from Transformers 3. As you all know Sam Witwicky's got a job in Transformers 3. When you are employed, you have to look professional. Coming from the set of Transformers 3, this is Sam's Briefcase: I won't be revealing the model or the manufacturer of the bag because then this thread would be an advertisement. Just for fun, there it is... Sam's TF3 Briefcase. P.S : For those of whom who wanted to know how I got this info, It's from the manufacturers themselves. Production unit ordered several of these for the shooting. TF3 production unit was kind enough to tell the manufacturers what the Briefcases will be used for.
