From the intricate Kinecar by William Heath Robinson to Stone-age cave paintings in Chauvet, France, they have captivated us throughout history. They tell stories of our past and present, like the American Flamingo beautifully depicted by John James Audubon or the Defence of Chateau de Hougoumont during the Battle of Waterloo. G. H. Davis's British 25-pounder field gun showcases technical precision while Audubon's Louisiana Heron captures nature's elegance. A. E. Bestall's The Last Caravan takes us on a journey through imagination, while extracting a weed from a lawn becomes an art form in A Garden Guide. Portuguese poet Fernando Pessoa expressed his soul through sketches, just as Da Vinci did with his crossbow design and can windows into history and creativity; they allow us to witness Napoleon commanding troops at Waterloo or appreciate Leonardo da Vinci's genius beyond painting.
