A familiar sight today, mailboxes weren't always a house-front staple. Letters were first hand-delivered to residents in urban dwellings in the mid-19th century. Wall-mount boxes didn't appear until the 1890s. Back then, some were made of glass; their transparency offered a convenient letter check. In these security-conscious times, wall-mount mailboxes are made almost exclusively of metal with weather-resistant finishes, and many have locks to secure homeowners' personal information. With bold graphics, raised design details, and a wide variety of finishes, today's styles are also larger to accommodate catalogs, greeting cards, small packages, and—of course—the latest issues of This Old House. Here, find 20 designs that will look at home on a wide variety of house styles.
