Last Friday I had the pleasure of visiting the Ogden Bicycle Collective. They provide refurbished bikes to kids and low income families, in addition to hosting educational programs. While snooping around, I came across these hand-written instruction sheets with hand-drawn diagrams. 

Derailleur Adjustment Instructions


Bottom Bracket / Crankset Instructions

The sheets looked photocopied, so I'm wondering where the originals came from. I figured out from this video that the "WTF Workshop" in the upper left corners refers to "Women Trans Femme Workshop." The video also refers to the sheets (at about 3:42):

But the original artist/writer is never named. Any clues out there? I really like the sheets and would like to track down a complete set...
