My Word with Douglas E. Welch

In the early 20th-century English fireworks company C.R. Brock and Company (now known as Brocks Fireworks) published colorful catalogs displaying designs from Japanese companies such as Hirayama Fireworks and Yokoi Fireworks. Six catalogs of diverse pyrotechnic diagrams have been digitized and made available for download thanks to the city of Yokohama’s public library. If you don’t read Japanese, you can download each publication’s PDF by visiting their website, clicking one of the book’s English titles near the bottom of the page, and then clicking “本体PDF画像” link below the image. Each catalog is a tremendous and varied selection of the firework shapes and colors of the time, with several designs you might recognize no matter where you view contemporary fireworks displays.
