Description
In 1840, the English mathematician Charles Babbage visited Europe, spending considerable time in the Italian city of Turin, where he expounded on the principles of his analytical engine. These punch cards represent his thinking about how the operation of a computing device might be controlled by punch cards.
One card is white on both sides. The other is tan on one side and grayish-brown on the other. Each card has round holes at both ends, as well as two rows of round holes in the middle. There also are cuts in the top and bottom edges.
