Here's some scans of some Tom and Jerry layouts and animation, plus a model sheet of Jerry. I think it was posted once by Jerry Beck on Cartoon Brew.
This one above is my favorite. I'm pretty sure it's from one of Irv Spence's scenes in Quiet Please. Check out Thad Komorowski's great posts about Tom and Jerry's animators here and over here, oh here too, and don't forget here.
