*DC: Edited in the 1950s by Whitney Ellsworth, My Greatest Adventure was one of a series of science fiction/weird mystery adventure titles from DC, which, although not up to the apex of the very high bar set by Julius Schwartz in Mystery In Space and Strange Adventures, nevertheless presented a consistent standard of story and art, including many issues, such as the four below, with Jack Kirby art.

#16 GD/VG £35 (PICTURED) Jack Kirby art. Small upper spine split, loose at top staple, some minor edge wear, unmarked copy. 
#18 VG+ £56 (PICTURED) Jack Kirby cover and art. Nice bright, solid copy with white to off-white pages and firm staples. Just a couple of very minor creases. 
#20 PR £6.25 Jack Kirby art. Horrible light blue grunge splat centre cover. Almost detached at spine. 
#21 GD £19.50 Jack Kirby art. Back cover tear and small chunk out base spine back cover.
