Sammy cels
From The Lost Media Wiki
Found the motherload of Sammy production cells. https://www.worthpoint.com/inventory/search?query=Sammy+David+Spade&category=&categories= Must be hundreds of backgrounds and character arts in there. Additionally, I've contacted a few directors on the series and some people involved with animation in the hopes they may have footage in their portfolio. If need be I will contact the sellers of these Sammy cels to see if they know anything about the series.
