A year or two later, people began tagging me in posts of people wearing t-shirts with the lettering on it, except the shirts weren't produced by me. It was also brought to my attention that vehicles bearing a decal version of the lettering were being seen, and I've never produced vehicle decals.
A quick google search verifies that the design has been stolen and is being widely sold without my permission. To be clear, I do not claim to own the actual phrase, "Stay Humble;" I'm the originator of the stylized lettering and artwork of the phrase.
Stealing art is wrong. A trademark has been filed.
These are screenshots of various online shops selling un-licensed variations of my art without my permission.
