How The Grinch Stole Christmas: Lost Sponsor Plugs

So it turns out there IS more deleted footage from the special beyond these sponsor plugs. This website shows a cel taken from the sleigh ride scene that isn’t in the final special:

It’s mentioned there and I believe elsewhere that the sleigh ride scene originally ran longer. By the looks of the cel this was to occur after the Grinch and Max make it around the curve but before he steps out of Max. Watching the final scene carefully you can notice moments where it looks like things were cut including this brief one.
