BOOM! Studios and its imprint Archaia Entertainment have published a number of comic books as one-shot specials exclusive to Free Comic Book Day (an annual promotion observed by comic book publishers every first Saturday of May since 2002). Some of these issues contain a collection of short stories from titles they publish regularly. Many of them have been the debut release for Labyrinth and Fraggle Rock comics before being reprinted in a franchise-branded trade paperback collection.
