series, called Numero Speciale (Special Issue), with one story longer than usual and, in addition, small extra books on various horror-related subjects. Another annual release was added in March 1991, L'almanacco della paura ("The Almanac of Fear"): together with Dylan Dog stories, it includes articles and curiosities about film, literature, and other topics, all related to the horror theme. January 1993 saw the appearance of a new annual book, the Dylan Dog Gigante ("Giant-Size Dylan Dog"), so called because it was much larger than the monthly book and because it contained more stories. Dylan Dog maxi came out in July 1998. This was another annual release that collected together three previously unpublished stories. Specials In October 1990 an irregularly numbered issue came out: Dylan Dog e Martin Mystère – Ultima Fermata: l'incubo! (Dylan Dog and Martin Mystère – Last Stop: Nightmare!). It presented an unpublished story in which the nightmare investigator teamed up with another famous Bonelli character, Martin Mystère. Alfredo Castelli and Tiziano Sclavi wrote and plotted this story, and Giovanni Freghieri did the drawings. The story had a sequel in 1992. Reprints The first reprint series came out in July 1990, the second in June 1991, and the third in June 1996, this time called Collezione Book (Collection Book); in October 2006 the bi-monthly reprint Grande ristampa was released. February 1997 saw the release of the Super Book, a tri-monthly release that reprinted the special annual issues that had come out ten years before. Dylan Dog Color Fest In August 2007, a new annual was released. Containing 4 new stories, the new comic book was called "Dylan Dog Color Fest" because it contained only stories full colored and not black and white like the regular series. In 2010 it became bi-annual (coming out in April and August every year). By 2016, each album would contain 3 colored stories – even though some albums also contain one individual story – and it would get published each number every three months. In November 2018, the 27th album will be released. Colored issues Dylan Dog (like all Sergio Bonelli comic books) is printed in black and white. However, there are some issues that came out full colored to celebrate certain anniversaries. These include numbers that are multiple of 100, decade anniversaries of the series and other rare occasions. The first full colored issue was # 100, titled "La storia di Dylan
