(CNN) Josh Marshall's tattoo is definitely cooler than yours.

The Kansas man noticed his young son, who's battling brain cancer, was self-conscious about the scar left behind on his head after a surgery.

So Marshall got a tattoo that matches his son's scar. A picture of the head-matching father and son was entered into the #BestBaldDad contest sponsored by the St. Baldrick's Foundation, a childhood cancer charity.

"Me and my son at this year's St. Baldrick's event in Wichita, Kansas. Got my son's scar tattooed to help his self confidence," Marshall wrote with his photo submission.

The pic was a winner, nabbing first place with over 5,000 votes and bragging rights for Marshall as the world's best bald dad.
