Description from MagKnits:

An oversized, tunic length cool sweater imitating the fashionable layered look of skater sweaters. I wanted to knit a real “big boy” sweater for my little son, but didn’t find any pattern that was “cool” enough. Then, I stumbled across 1000 Great Knitting Motifs by Luise Roberts and found graffiti guys in it. She has three different guys of which I only liked two, but they were too small for my purposes. Thus, I enlarged and modified the two (No 1 and 2 on the chart) and invented another four guys. Here is the result, a sweater for little boys to make them feel great.

This is a fairly easy sweater as the gym-guys are embroidered onto the sweater after finishing. The only challenging bit is the sleeves.
