I don't know who drew these Alice poses, but the original artist is Marc Davis. Either a clean-up artist or a rough in-betweener traced off a few of Marc's key animation drawings.
This kind practice gave follow up artists the opportunity to get to know the character in terms of shapes, lines and volumes.
Quite a few studies like this one survived from Disney's golden and silver age. It was very common to study the lead animators' art, before adding assistant work. They are mere tracings, but I detect a pretty good understanding of the delicate realism involved in a character like Alice.
