Sam & Max - unpublished comic strip

I managed to acquire this - to my knowledge - unpublished comic strip from Sam & Max. I'm excited! I didn't find it in the Telltale collection so I'm wondering if it's actually been published anywhere. But with no wording (as far as I know all Sam and Max comics have wording) I'm pretty sure it's unpublished. So what was Steve planning in terms of dialogue? We'll probably never find out but it must have been brilliant!

Update
I reached out to Steve to get some more info on the piece. This is what he had to say: "that piece wasn’t published unless I put it in one of my printed sketchbooks. Can’t remember. It was done for a comics writing camp class I did for teens so they could write their own dialog for the panels. I have a copy somewhere that author Ridley Pearson wrote into when he sat in on the class. Anyway, the answer is that I never created my own default version. It’s whatever you want."
