Stacks of Plaques Guarantee of Authenticity for Muhammad Ali

This is a formal 'Guarantee of Authenticity' certificate issued by Stacks of Plaques, Inc., specifically for a hand-signed signature by the legendary boxer Muhammad Ali. The document is printed on light blue paper stock and features a decorative dark blue or black border. At the top, it bears a graphic logo 'STACKS OF PLAQUES' depicted under a silhouette line of various athletes including a basketball player, golfer, baseball player, and tennis player. The central text officially congratulates the owner and guarantees that the item purchased features an authentically hand-signed signature of Muhammad Ali. In the bottom right corner, the certificate is signed by Lou Scalia, the President of Stacks of Plaques, Inc. This document serves as a 'Certificate of Authenticity' (COA) which is a crucial provenance element for sports memorabilia. Physically, the item appears to be in a protective plastic sleeve or album page, showing some slight reflective glare but otherwise clean edges and no visible creasing or staining. The typography is a mix of serif and bold sans-serif fonts, characteristic of late 20th-century commercial printing for collectibles. This type of documentation was common in the 1980s and 1990s when Muhammad Ali held numerous signing sessions with organized memorabilia companies.
