I came across a website today that offers interesting ways to produce portfolios that you can send out to galleries or clients. The company is called Shinebox Print and they specialize in books of cards that have a flap which wraps around all the cards. Each card in the book can have a different front and back image in order to show a variety of your work. You can mail them out as an entire booklet or tear out individual cards and have your contact infomation and Patron gallery address printed on the back. Each large size book is around $17 a piece when you buy 10 and you can view some samples here.
