Here's a recent one I did for the Weekly Alibi for an article on Bank Transfer Day. Bank Transfer Day encourages people to take their money out of the Big Banks and switch to credit unions.
"Unlike banks, credit unions are not-for-profits owned by their members. Instead of siphoning earnings up the pipeline to shareholders and CEOs, they can invest them as they see fit. This can take the form of lower interest rates and fees, or member-directed donations to local charities and community groups. Perhaps most crucially, they can respond to local economic conditions and offer loans to people who might not qualify at a big institution." (For the rest of the Alibi article, click here.)
The art director requested a portrait of Guy Fawkes on a bank note that had a number of references to Bank Transfer Day (the date, "99%", ninety-nine percents) so I did two versions, one of Fawkes' actual face and one of the iconic Fawkes masks. I was wondering which one they'd use -- they ended up using both! The article describes the historic origins of credit unions and the anti-Big Bank sentiment that is a form of protest today. Using versions became part of the concept, which was a fun surprise.
