The first page of the Ponyville album from the first released version of the game. The left page features Twilight Sparkle, Bon Bon, Mrs. Cup Cake, and Cheerilee, and the right page features Snails, Dr. Hooves (as Time Turner), Zecora, and Lyra. Twilight and Bon Bon have been welcomed and are not grayed out; Twilight has one star and neither of them have been assigned to a shop.
The album was part of the game interface which showed the characters available to be welcomed. Characters which haven't been welcomed yet were grayed out. Two pages were shown at a time, with each page featuring 4 characters, and each character's entry indicates that character's stars and the shop where they work. Ponyville, Canterlot, and Sweet Apple Acres had separate albums.
This should not be confused with the album page each character has showing their description and minigame information.
After Update 2.4, the album was replaced with Collections.
