LEGO is giving out a very cool LEGO Marvel Super Heroes Thor: Ragnarok poster at San Diego Comic Con 2017, most likely on accident. This poster is supposed to be given out on Friday and Sunday while the LEGO DC Comics Super Heroes Justice League poster should have been today and Saturday according to the poster artist Tom Whalen. He will also be doing signings at the booth in Saturday from 3-4.
LEGO has given an update to the confusion. Today and Saturday is for Thor: Ragnarok while Friday and Sunday are for Justice League.
