Pig crossing:

From the liner notes:
Willi The Pig was recorded at the first incarnation of the Willisau Jazz Festival, Switzerland, August, 1975. The LP was released a year later in an edition of 500, with a beautiful hand-printed cover designed by the festival's director Niklaus Troxler. Never reissued, it became a scarce collector's item. Asked which of her out-of-print records she'd most like to see made available, Irene Schweizer immediately mentioned Willi.
