Directors' homage to old films

Late in the film, George and Lucy talk and stroll down the city sidewalk and pass The Bijou Moving Picture theatre. Many early theatres were named Bijou.

Look at the DVD of this great film. At 1:00:10, the pair starts passing that movie house. Displayed in the background are marquee posters advertising films that actually were made. The following were all real 1912 short films:
The Mis-Sent Letter
The Bugler of Battery B
Ten Days With a Fleet of U.S. Battleships (documerntary)

Most striking is a sign advertising the name, G. Melies, who was French producer-director Gaston Méliès, who directed 75 films between 1903 and 1914, according to IMDb. The film advertised on the sign was his Ghosts at Circle X Camp (also 1912) that he filmed in Santa Paula, California. Most of his films were made in France.

If those posters were authentic, they'd be worth a fortune.
