Duke's is more than just mayonnaise. It can also be a free tattoo.

RICHMOND, Va. — Sandwiches, salads, deviled eggs and...tattoos? Duke's Mayonnaise might just become the most tattooed mayo brand in the world after a unique pop-up event they're hosting in Richmond with Yellow Bird Tattoo.

Die-hard Duke's mayo fans can sign up for an appointment to get a free, flash tattoo at the shop during the event on May 13. The tattoos will all be related to Duke's or mayonnaise in some way — but all of the pre-drawn designs on the flash sheet that you can choose from won't be revealed until the day of the event.

The limited appointment slots open at 11 a.m. on April 27. You can find out how to sign up on Duke's social media pages. Appointments are first-come, first-served, but there will be a waiting list.
