Yesterday's Art is Today's Pornography

La maja desnuda (known in English as The Naked (or Nude) Maja) is an oil on canvas painting by the Spanish painter Francisco Goya (1746–1828), portraying a nude woman reclining on a bed of pillows. It was executed some time between 1797 and 1800, and is sometimes said to be the first clear depiction of female pubic hair in a large Western painting. The painting is in the Museo del Prado in Madrid.

Formerly considered art, now considered pornography.

Ironically, the following picture was considered pornography when it was initially published in Playboy and now this is considered Art.
