Has anyone seen this wordmark/logo for the ISO 9660 filesystem before? I found it on a "Night Owl's" shareware CD-ROM, and cannot find any info on a potential source. I do have a copy of the ISO 9660:1988 standard, and it isn't included there. This logo is appearing before any of the 2000s revisions. I've since found it on a couple other shareware CD-ROMs: Gigabyte Shareware and Shareware Extravaganza, but not on any non-shareware CDs. Maybe it was an unofficial design shared by shareware nerds?
