Scandinavian Toilets is a collection of over 100 toilets as seen and used by myself while living and traveling in Scandinavia (Norway, Sweden, and Denmark). There are 12 editions in total, and each is hand bound using the coptic binding technique.
The front cover is made of a relief print based on two separate toilets, which splits the collection in half. Six with a urinal and Six with a standard toilet. Each book is comprised of about 4-5 hours of work.
A gallery of all of the toilets is available online here.
More information about the relief printing process can be found here.
