This 'Undertow' shirt isn't actually from the Undertow era at all, but rather from a post-Lateralus point in the mid 2000s when Tool was revisiting several themes from previous albums. Having come out long after the expiration of their 1990s merchandising contract with Giant, this, along with most prints of this era, was printed on a generic Anvil shirt, and the graphics have held up very well with only a slight fade.
