This Transformer may be a bit downsized, but it makes no difference to the delighted little girls who witnessed this.
The Ann Arbor, Michigan street performer known as NOLATron, aka Joslyn Alana Paige (according to her Facebook info) is the person responsible for this wonderful bit of CosPlay. With the help of her friend, Jason Beck she built two. She kept the yellow Bumblebee Cadillac Escalade and gave a blue prototype to someone else.
NOLATron keeps regular street hours from Friday-Sunday 9:00 am-4:00 pm on various downtown Ann Arbor street corners.
