A few days ago pictures were posted of some large detailed prop as it was driving to an unknown destination in Michigan. Thanks to an image provided by Mark S. here is an image of a new prop that might have something to do with Transformers 4 that was taken at Design Concepts in Plymouth, Michigan.. At least it seems likely part of TF4 filming as not sure of what other movie in the state might use something like that. I can't tell if its the same ship prop from another angle, a completely different one or maybe another piece of the whole. We will likely find out for sure soon as production continues in the state for the next few weeks.
