Our Services

Defunkd has been immersed in the world of vintage T-shirts since 2004, building one of the industry’s most trusted resources for collectors, enthusiasts, and sellers. In 2010, we created the blueprint for vintage T-shirt authentication through our community forum, creating a space where collectors could seek expert opinions, identify counterfeits, and share knowledge long before authentication became a widespread concern in the industry.

Over the past several years, we’ve continued to develop our expertise through hands-on research, in-person authentication, and the ongoing development of comprehensive certification and grading.

Backed by more than two decades of experience and our extensive archive of vintage T-shirt knowledge, we’re now making that expertise more accessible through a growing range of professional authentication and advisory services.

Whether you’re considering a purchase, questioning a shirt’s authenticity, or seeking a deeper understanding of a treasured piece, Defunkd is here to help you buy, sell, and collect with greater confidence.
