From Funko’s blog:

Free Comic Book Day is this Saturday – look for Unmasked Tony Stark & Steve Rogers Civil War Dorbz exclusive to this event!!

Visit freecomicbookday.com/storelocator to find a store that is participating in this event. We recommend contacting your local store to find out if they will have the Dorbz in stock. Each store will have their own method of distributing these special Dorbz

Get on out there on Saturday and pick up a few comics, hunt for Dorbz, and support your local comic book store!
