Here is Eduoard Manet's Le Déjeune sur l'Herbe (Luncheon on the Grass), a painting rejected for the presitigious Salon exhibition of 1863. Classical nudity was respectable in Academic art at the time, but the presence of fully clothed gentlemen indicated that this was a contemporary and therefore scandalous scene.
It didn't help Santa's reputation at the time, either.
Okay, the original did not have Santa Claus. Over the past 25 years, photographer Ed Wheeler has taken self-portraits while dressed as Santa. He often digitally inserts himself into famous paintings. You can view more in the series here.
