Although it was first settled in the 1830s, Oak Park did not become an independent municipality until it split from Cicero Township in 1902. No longer a rustic small town, the village soon became a population magnet, attracting ever-larger numbers of prosperous, progressive people to settle in what many soon referred to as "the finest of the streetcar suburbs."Coincidentally, use of the penny picture postcard had approached a national mania during this era. Thus from the earliest years of the 20th century, the rapid growth and development of Oak Park was well documented, even celebrated, with a vast and varied array of outstanding postcard images.
