What do Philadelphia, San Diego, San Francisco and New York City have in common? The names of those cities produce some of the best ambigrams we could find in our world-wide hunt.

The exquisite “Philadelphia – City of Brotherly Love” ambigram by John Langdon garnered the highest score, and took our top prize. Congratulations to John and to Philadelphia!

There are books with ambigrams, and books about ambigrams, but how do you learn how to create your own? Nikita shares a gem he discovered.

In “Angels and Demons”, Dan Brown states that ambigrams are four hundred years old, but the known history of ambigrams is quite a bit shorter.
