caption: The image shows an old book with a drawing of a horse on it, titled "William Killingly Sadler, No 26, the Golden Horse in Coleman Street, London". The horse is depicted in a majestic pose, with its mane and tail flowing in the wind, and its hooves kicking up dust as it gallops across the page. The text on the book is written in a classic font, and the background is a deep blue, giving the image a timeless feel.
