A drawing in the Paul Mellon collection and an engraving by A. Walker both seem to relate to a similar painting of 1755 also in the Mellon collection. According to a catalogue of the Hollis collection, Hollis is depicted in the foreground with his friend Thomas Brand, his servant Francesco Giovannini and his dog Malta. Canaletto appears to have depicted himself seated sketching on a low stool and wearing a hat and long gown.
