I can't get an accurate age on this fabulous old mirror

There is the remnants of a FORD sticker, but no part number, no engraving

mirror glass is in surprising good condition

"There’s no definitive record pinpointing an exact timeframe when Ford rear vision mirrors exclusively used paper labels, as this detail is not well-documented in automotive history. However, based on available information about Ford’s manufacturing practices and the evolution of rearview mirrors, I can provide some context to help narrow it down.Rearview mirrors in early Ford vehicles, particularly from the 1910s to the 1930s, were often simple and utilitarian, sometimes featuring basic materials like paper or cardboard backing for branding or instructional purposes. Paper labels were occasionally used in early automotive components, including mirrors, to indicate the manufacturer, model compatibility, or installation instructions. This was especially common in the Model T era (1908–1927) and into the early 1930s, when cost-effective production was a priority, and mirrors were not yet standardized with etched glass or metal branding.By the 1920s, Ford began incorporating more standardized interior rearview mirrors, especially with models like the Model A (1927–1931). These mirrors sometimes had paper labels or basic adhesive markings, particularly in aftermarket or replacement parts, as a cheap way to denote origin or specifications. However, as manufacturing advanced, paper labels were largely phased out in favor of more durable methods like etched glass or metal tags by the 1940s, especially with the introduction of inside-mounted mirrors by companies like Cadillac and later Ford.The use of paper labels would have been most prevalent"  :
