|The Popular Magazine, July 1906 cover commemorating the 130th Anniversary of the American Declaration of Independence|
Street and Smith always did a good job with seasonal and event themes on magazine covers, putting out New Year, Thanksgiving and Christmas themed covers for a long time from the 1900s to 1920s. This is one of them, a photographic cover.
Strangely enough, in 1926, the year of the 150th anniversary, no special covers on the Popular. I wonder why.
