I produce these stickers and t-shirts, and have distributed over 25,000 stickers in the last four years!  Stickers are always available via eBay (or find me at a conference).  Shirts are for sale twice a year.

All shirts and onsies range from $16-$21.

Profits from the shirts ($1-$4 per shirt) are sent directly to TODOS, Mathematics for all, which is a professional organization that advocates for equity and excellence in mathematics education for ALL students – in particular, Latina/o students.

Store open October 29 – November 9!
