The City of Des Moines has a city flag. The flag was designed in 1974 and symbolizes the three downtown bridges over the Des Moines River. The flag was retired in the 90s, but a campaign to bring it back happened in 2019 and it flies again! June is Pride Month, you can purchase a PRIDE version of the official Des Moines City Flag.
A big Des Moines flag will run you $30. Mini flags (think Fourth of July flags) are available for $2 each and you can purchase a Pride Des Moines Flag sticker for $2. Of course, all of these versions and more are available for the non-Pride version of the Des Moines City flag. All of these items can be purchased at flagsofdesmoines.com.
