Drew this back in 2022, thought I'd share it here because I haven't!
thank you so much @anistarrose for providing the ID below!
[Image description: digital art of Dipper and Mabel from Gravity Falls in their designs from the unaired pilot. Dipper has slightly fluffier hair in a different shape, and both have slightly different color schemes.
The first image shows them in the attic, with Dipper reading from the "Book of the Damned" and looking up at Mabel with a grumpy expression. She's resting her arm on his hat, and her chin in her elbow, looking slightly amused.
The second image is the same, but with a gray background instead of the attic. End description.]
The long lost Gravity Falls "Next Time On," reel has FINALLY been found!
This right here is what made this show happen and the reason why every new Disney cartoon also has a next time on reel. GF's last big lost media hunt is over!
Alex Hirsch said that he was okay if this ever was to leak. So, if this goes down, blame Disney!!
