Are those sketches of penguins?

Penguins unexpectedly cover the first page of a 1939 sketchbook in the Henry Daland Chandler papers. The rest of the sketches within the book are detailed and shaded images of Bermudian buildings created with the critical eye of the professional architect, Henry Daland Chandler. These penguins from the Bermuda Aquarium add a delightful and personal touch to this small volume.

I nominate the chubby grump in the lower left corner as “cutest penguin.” Do any of these penguins speak to you?
