Image description: Two drawings of a roofless horse-drawn carriage with large spoked wheels, possibly a phaeton. A man is sitting on the driver’s seat. In the first drawing, a horse is pulling the carriage quickly. In the second drawing, the horse is running off into the distance with one pair of reins flying behind it. The man is sitting on the stationary phaeton, holding the other pair of reins, which are attached to the end of the traces, and which have triggered a device which released the horse from the carriage.
