Today, over on their official Facebook page, ConventionExclusive.com announced that they would have a SDCC variation of their Stan Lee Pop Vinyl figure as an exclusive at SDCC 2014:

Look who we’re bringing to ‪#‎SDCC‬
Our #SDCC ‪#‎StantheMan‬ pop will be available at booth #716 Cross Country Collectible/ConventionExclusive.com
As we did at ‪#‎NYCC‬ we will have an allotment per day to give those with one day passes an opportunity to get one. We will be giving tickets out based on 1st come 1st serve. DO NOT LOSE your ticket. With the ticket you are guaranteed one Stan. This will only allow you to have fun throughout the day without standing in a massive line. You MUST pick-up your Stan Pop no later than one hour prior to the show closing that day. Any Stan’s not picked up will be sold out right the last hour of the show every day.
