The ambigram challenges just keep getting better. For this challenge, the winner will get an aerospace-grade titanium ring with their design deep engraved into it!

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!
