LEGO has just revealed some of the exclusives that will be sold at San Diego Comic Con 2016 with the Super Heroes BrickHeadz. These sets are just previews of the full line which will be coming in 2017. Each set will be sold each day at SDCC for $40 each.
In order to purchase the sets at the LEGO booth (2829), attendees must go to the Pavilion Terrace to participate in a random drawing to qualify to buy which begins as early as 7am each day. If you qualify, you take your voucher to the LEGO booth and make your purchase there.
