This is a panel from "Smile Thieves," one of my comics. It's a scifi about 4 heroes who are labeled "smile thieves," as the currency of the planet they're on is smile energy. They've discovered that smiling is an infinitely free source anyone can use. The government has hypnotized populations into believing it's limited, that you can only smile so much.
