I got the french version and checked a few of the known alterations in the later releases.

The Baby Herman middle finger is there.

The Betty Boop nip-slip is there. This is the only version I've seen that has this.

There are a few frames during Jessica Rabbit's musical number where the slit in her dress looks like it might be a little more revealing (even though you don't really see anything). There are rumors that the theatrical version had a frame somewhere that shows her panties/vagina but every story claims it's in a different spot and there's not solid evidence.

The scene with Baby Herman smoking in the baby carriage appears to be unaltered. There are some reports that the scene was altered but I haven't found any proof.

The scene with the writing on the bathroom wall matches all the other versions I've seen. I've yet to find any proof that the phone number was ever actually there. One version of the story claims that the number was in place throughout the scene and people were calling Michael Eisner's home number because of it. Other versions of the story claim it was only there for one frame or that it was Jeffrey Katzenberger's number instead. Another version of the rumor claims that people didn't find it until after the laserdisc was released but I remember hearing people claim the phone number was there before the movie was actually released on home video.

The scene with Jessica Rabbit's panty-shot is unaltered.

There are various dubious reports of different clips that were edited out, but solid proof has never been offered.

I haven't done a frame-by-frame comparison yet, so there may be other differences. The blu-ray version uses the same transfer as the Vista Series DVD, so it will have the same alterations.

Edited the correct and update some information.
