How do you reach a lot of people at a big event? SXSW is a huge annual music (and now, interactive media) event in Austin, TX. With loads of people to reach, and perhaps smaller budgets than in years past, the answer seems to be custom stickers and buttons. For an idea of scope, check out how many tote bags the conference gave away a couple years ago. After the jump, a couple more images of buttons and stickers from the conference.
