I went to Lilly recently and they told me anything less then 4 photos and you'd have to pay a $20 surcharge. Maybe I misheard them. If it is 10, as the major says, then here are 10 Ambersons photos at Lilly for which I think negatives should eventually be made, if some person (or persons) can scrape together enough cash. I'd love to myself, but finances are a little tight right now.
1. BOX 33, Folder 1, picture 31
From a missing section of the ballroom scene, Closeup of Jack and Eugene discussing George with a mirror reflecting dancers between them ("Just wait until you know young George a little bit better"). Needs a negative.
2. BOX 33, Folder 5, picture 182
Also a missing section of the ballroom scene, a low-angle shot of Fanny, Isabel, Eugene, and Jack as they discuss the wrinkles that age puts on faces. Needs a negative.
3. BOX 33, Folder 5, picture 196
Jack and George at the railroad station, an angle I've never seen in any Welles book. Don't know whether it has a negative or not.
4. BOX 34, Folder 1, picture 211
Missing scene: Eugene walking to Amberson mansion with flowers for Isabel, to apologize about the bass fiddle. Don't know whether it has a negative or not.
5. BOX 34, Folder 1, picture 236
Missing FOTA clubhouse scene: Boys raising hands to say "Aye!" ("All those in favor of holding a new election say "Aye!"). Needs a negative.
6. BOX 34, Folder 2, picture 251
Ballroom scene, Fanny, Isabel, Eugene, and Jack. Same as #2, but from a straight-on angle. Needs a negative.
7. BOX 34, Folder 2, picture 256
Missing scene: Isabel (partially in shadow) writing a letter to George renouncing Eugene. Has a negative.
8. BOX 34, Folder 2, picture 263
Missing bit of ballroom scene: Jack and Eugene discussing George, but from a low-angle. Needs a negative.
9. BOX 34, Folder 7, picture 445
Priceless behind-the-scenes shot of Welles sitting on Santa's lap (with a pipe in his mouth if I remember correctly). Don't know whether it has a negative or not.
10. Great behind-the-scenes publicity stills of Ambersons cast strolling arm-in-arm across the RKO lot. Can't remember the Box and Folder number though. Don't know about negative.
These to me were some of the most striking of the Ambersons pics at Lilly, and were ones which I've never seen anywhere else. But there are many others too: Boxes 33 and 34 contain nearly 500 Ambersons photographs!
