This tag is intended for anything that feels greatly outdated.

This can include video clips from an old cartoon or any art piece the predates e621 itself (the earliest posts here only go back to February 10th, 2007)

A more recent art piece can also meet this criteria if it is presented entirely through a vintage video/audio filter (VHS, phonograph, etc.) or has an art/animation style that blatantly reflects the 90s or earlier
