Most people are unaware of it, but in 2003, the American Film Institute assembled their list of the 100 greatest American movie posters. Reproductions of the entire collection were made available for purchase through MovieGoods, now defunct. I have a Pinterest board of the 100 selected posters here.
The effect for this list is kind of blunted, since there's no way to display the specific poster AFI chose. If you click the above link to MovieGoods, you can see each of the exact selections.
#29 The Invisible Man (1933) also appears at #59 on the AFI list, but only appears once at #29 here
#39 The Bull-Dogger is a lost film and is not included here
#55 Stolen Love is a lost film and is not included here
