Here's a dump of the show flyers I've collected.
Some via archive.org snapshots of missionshifter.org and suckrock.com
Others are from instagram @massflyersarchive and tag #missionshifter
(This was the THIRD punk rock xmas held in 2000, which means maybe Sol and other young homies hosted it? All missionshifter guys graduated in 99 or may 00)
