The Son of the Sheik Movie Posters

These are two posters from the film,"The Son of the Sheik." The last poster is very common; however, the first one is a rare variation. The second poster is very interesting. It states the movie starts Friday, the 20th with the midnight matinee. Friday the 20th was in 1926, so in essence this was an advance poster. Also, Friday the 20th, was three days before Valentino died.
