There doesn't seem to be an end to these (we got through 65 before I got bored and quit). It's a lot like Hangman. In some cases, you can figure out the title without having seen the movie. On the other hand, I take issue with some of what they call "classic" movies, either because I've never heard of them, or because the item shown isn't what I first think of as a famous object.
The baby carriage from Battleship Potemkin is a famous object. So is the Stay-Puft Marshmallow Man from Ghostbusters. The ukelele(? it's been a long time since I saw the movie) from Some Like It Hot is not a famous object; nobody ever talks about Marilyn Monroe's great ukelele scenes.
