From Erin Glover on the Disney Parks Blog:
After a short closure, Blue Sky Cellar opened again today with new sneak peeks and behind-the-scenes looks at the continuing transformation of Disney California Adventure park. Guests will be able to view new videos, models and renderings to learn even more about the exciting changes coming to the park. Among the new artwork, you’ll also find three new attraction posters, including the one above featuring the new Red Car Trolley, coming to Buena Vista Street when it opens next year.
If you would like to see more photos, our good friends over at SoCal Thrills have a detailed photo report covering the new exhibits.
