Land's cover art for Aliens: The Original Years Volume One sparked controversy after fellow artist Tristan Jones accused Land of tracing his work, specifically several pieces of concept art for the comic Aliens: Defiance. Jones would subsequently post evidence showing how Land's cover artwork showed glaring similarities his own pieces. Several sites noted how this was not the first time Land had been accused of plagiarism in this manner. Subsequent to Jones' complaint, fans found further evidence of tracing in Land's cover art, including similarities between the Egg in the bottom left corner of the cover and a replica sold by NECA.
