This is a book I rescued from the garbage at work. It is a collection of (fake) letterheads printed on 'Bankpost' This book is actually a sample book for stationary paper. The letterheads were designed by 5 famous Dutch Designers from the sixties and seventies such as Wim Crouwel.
In my work as graphic designer I've designed quite a lot of letterheads however they look a lot different from the ones I show here. Office stationary has changed a lot with the use of Word templates. These days most of the effort goes into designing the inprint. And the only design choices I seem make in this proces are 'do I use Verdana or does Arial look more appropiate?'
