I have a huge antique photo portrait signed by Burger & Reed of Milwaukee, who were in business 1896-1900. The photo is 36" x 22" in very high resolution. I haven't been able to find any other 19th century photo this large with such a high resolution. Does anyone know how such a photo could have been enlarged using equipment available at that time? I am a longtime dealer in antique photos, and this one surprises me by its size & quality. Also, I am brand new to the Forum. Thanks for looking.
