I Just Love Firework Display,

both as a kid,

  and now, so I was intrigued to see these early illustrations,

 of fireworks, or I should say how they would look when sent up into the sky,

 in the early 20th-century English fireworks company C.R. Brock and Company (now known as Brocks Fireworks) published colourful catalogues displaying designs from Japanese companies such as Hirayama Fireworks and Yokoi Fireworks,

 six catalogues of diverse pyrotechnic diagrams have been digitised 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 catalogue is a tremendous and varied selection of the firework shapes and colours of the time, the catalogues also give advice on how to view the fireworks,

and prepare them, I guess the same thing happens today with firework manufactures, but instead of having a book they now have a video catalogue of what fireworks can be purchased for your own event.
