A 1930 advert for 'plastic surgery' by the Hystogen Institute. A quick look online shows that the Institute went into voluntary liquidation in 1929, but apparently survived or was resurrected. They were also sued by an ex-employee who was talked into having unnecessary surgery and left scarred in 1927. So if you are looking for rhinoplasty (the phrase 'nose job' conjures up unwanted images) then beware.
