What is now called retro art is a kind of pop art built between the 1940s and 1950s, in response to the need for a bold and eye-catching graphics that were easy to reproduce with simple presses. Easily distinguishable by modern style, computerized retro advertising art has had a resurgence in popularity thanks to quotations and parodies of old pop art works.
The so-called retro erotica is a type of photography that harks back to the pin-up style or pornography in the 1970s and earlier. It ranges from hardcore pin-up style without naked, often with lingerie, girdles, bras, Garter belts and pantyhose with hairstyles, makeup and props of the respective periods. Some fans distinguish the retro erotica (modern photography in old style) from vintage erotica (photo or film really), while others use both expressions interchangeably.
