What are these postcards

In late 2015, we held a referendum.

Thousands of listeners from around the world decided between five contenders for "official flag of Hello Internet".

According to our rules, ballots were sent on the back of postcards.

On this blog we're sharing some of them.

You can hear the vote count here or watch it here.
