The 1956 American film The Solid Gold Cadillac was released in what was then Yugoslavia, with the Croatian title Zlatni Kadilak. This poster (partly in English, partly in Croatian) advertises that release.
Starring Paul Douglas and Judy Holliday, this romantic comedy is about a minority stockholder (Holliday) who takes on the corrupt board of a multinational company. The movie was filmed in black and white until the last scene, which was in Technicolor.
If you love vintage movie posters, this is a fun one to add to your collection.
