These images have been painted in an archaizing Safavid style. Usually, Qajar artists associated erotic scenes with the Safavid period. According to the museum's website, "The gold-painted accents, facial features, Chinese-inspired rolling clouds and the use of colored papers are all indications of the Safavid painting tradition. However, it is thought that it is likely that this work dates from the later Qajar period. The reason, apparently, according to the museum is that many erotic images were intentionally painted this way in hopes of attracting foreign collectors into paying more for its perceived antiquity.
