A "BOTTOMS UP" card can be seen in this promotional photo for a prototype Sinclair machine.
The BOTTOMS UP card is also fascinating because it ties the 'Miller Animals' of the mid-1950s to the MOLD-A-RAMA machine of 1962. The figure that the hand is holding in the BOTTOMS UP card is NOT the elephant that we would have expected (the one from a MOLD-A-RAMA machine at the time), but rather it is a MILLER ELEPHANT presumed to be from the mid-50s! The shape of the ear, and ripples in the elephant's skin, are a perfect match! (See below, MILLER elephant on left, elephant from a machine original operated by Mold-A-Rama on the right) The base with 3 holes is quite the mystery though, both because it is one more hole than the machine makes, and also because the Miller animals have no base!
