Despite the ongoing rise in mass shooting numbers, America still lacks commonsense gun laws. This is an issue hard to touch inside Congress, mainly because each state has its own laws.

Because the U.S. government was not acting on the subject, we directly attacked a trait Americans are most known for: their pride for their land. Change the Ref created the Shamecards, a postcard collection designed to demand gun law reform from Congress. Subverting the traditional greeting cards, which depict each city’s landmarks, ours show what cities are becoming known for: mass shootings.

With no budget, we gathered artists across the world to illustrate more than 50 postcards, at least one for each state, making this a national campaign, and we made them available at shamecards.org. With a few clicks, they were sent directly to lawmakers’ mailboxes. Within seven days, thousands of postcards were sent.

The iconic 20th-century American postcard shows off pride for a town or city. Since 1931, this design became emblematic, depicting American landmarks, portraying a positive view of the country from its smallest towns to its grandest natural wonders. That was what America was known for, but sadly this is changing due to the lack of gun law reform.

Subverting Curt Teich’s traditional postcard design, we kept the blocked letters in the center of our art direction, and we subverted them to show the horrific story of mass shootings in each city. At first glance, the postcards look beautiful and colorful, but with a closer look, you realize how horrible it actually was.

With 53 postcards, with at least one for each state, we used 30 artists worldwide to illustrate the collection and remind politicians that we need to change gun laws before they change us.
