Really don’t know what to make of this hat. Don’t know if it is a misprint or someone added a misprinted patch to an original Imperial blank made in Denver Colorado 1970’s. Liner reads genuine Leather. Here’s what Ai had to say: The interior tags firmly identify this as a vintage 1970s Imperial Headwear cap manufactured in Denver, Colorado.The specific design features confirm its authentic retro construction:The Manufacturer Tag: The "Imperial America's Finest Headwear Denver, Colo." tag text and styling align perfectly with Imperial's production runs from the 1970s and very early 1980s.The Sizing Strip: The stamped paper/fabric sizing scale underneath the sweatband (showing fractions like \(6\frac{5}{8}\), \(6\frac{7}{8}\), 7) is a classic indicator of mid-century to late-20th-century blanks before standard plastic snapbacks or generic "One Size Fits Most" tags took over completely.The combination of this specific Denver-made Imperial blank, the single-stitched typo front patch ("Oakland Raider"), and the braided rope details make this a highly unique, authentic piece of vintage NFL memorabilia.See photos. Any questions ask. Have a good day!
