California or Bust - Original Trade Ad 1925 - Richard Dix, Duesenberg
Originally titled "Racing Hearts" on its first release in 1923, it played far better as "California or Bust" on its re-release in 1925.
This Trade-ad is the only one I've seen, and as for a full sized poster; I doubt that one exists. If it does, think high five figures.
This is also double sided, giving full details of the movie on the obverse. It has a protective backing sheet that still allows viewing of both sides.
NEW: I've added a pic of the reverse side.
Origin: USA 1925 Size: 12 x 9 in / 30 x 23 cm Condition: Excellent. Double sided. Ask for details
