He's done this sort of project before with the Mozart Operas, which he made into a luxurious photobook that you can purchase online (click here).
At any rate, he asked me to do some concept logos for him. He may or may not use them, but I came up with a variety of designs and styles which I thought worth sharing here.
Please keep in mind that I am by no means a professional graphic designer. I write books. I've only learned how to do minor design in the last five years due to the necessity of learning the self-publishing industry. But I've grown to like it as a hobby.
The name of the project is "A Steampunk Guide to Hunting Monsters." It basically will be half photo book and half written narrative done up in a fancy late 18th early 19 century style newspaper articles talking about monster hunters (basically monster stories) set around the globe in a steampunk world.
As such, the designs relate to the various combinations of cultures and time periods, such as Western-Steampunk, Oriental-Steampunk, and so on.
I hope you enjoy!
