Widely available by the 1950s, aluminum awnings were touted as longer-lasting and lower-maintenance than traditional [canvas] awnings. . . . [T]hey were especially popular with homeowners. Aluminum awnings were made with slats called “pans” arranged horizontally or vertically. For variety and to match the building to which they were applied, different colored slats could be arranged to create stripes or other decorative patterns.
