About Us- Custom Trading Cards and Custom Baseball Cards


One of One memorabilia cards were first created when founder Omar Cornelius’s deep dedication for collecting sports cards collided with his passion for family following a decision to spend time being a stay-at-home dad. Together with son Eli, the pair embarked on an exciting journey and gradually turned a unique hobby into a full-time business. These days, every One of One card is handcrafted with the utmost care to ensure you are provided with a truly authentic memento that you can cherish forever.
