in 2014. Mighty Marvel Masterworks trade paperbacks (2021 - present) Beginning in June 2021, Marvel started releasing a new trade paperback line called Mighty Marvel Masterworks. Originally nicknamed as Junior Masterworks, they aim to reprint classic stories in an affordable price for young readers, as to capitalize on the growing popularity of super-hero media, so the trim size is smaller than the average comic book trade (6" by 9"), resembling a Manga volume. Golden Age Masterworks (2004-2012) In October 2004, Marvel released its first Golden Age collection, Golden Age: Marvel Comics Vol. 1, launching a new line of Masterworks. This 1939 and 1940s line reprints material by Timely Comics, Marvel's Golden Age predecessor. It is differentiated from the 1960s Silver Age line by the words Golden Age on each title, and with the regular dust jacket colored gold rather than silver. From Golden Age: Captain America Vol. 1 (February 2005) onward, these volumes were released quarterly. The line was discontinued in 2012. Atlas Era Masterworks (2006-2013) In January 2006, with Atlas Era: Tales to Astonish Vol. 1, Marvel began publishing a third line of Masterworks, reprinting 1950s and early 1960s comics of Marvel forerunner company Atlas Comics. The regular editions of these volumes have red dust jackets instead of silver. The comics reprinted in these volumes were originally produced during a lull in superhero popularity. The initial Atlas Era Masterworks volumes were primarily science-fiction/fantasy stories, particularly featuring drive-in theater-style monsters. More recent volumes have included other genres, such as pre-Comics Code horror and jungle stories. Marvel started publishing the Atlas Era Masterworks volumes semi-annually, then quarterly before returning to semi-annual. The line was discontinued in 2013.
