My portfolio is comprised of 12 each 11X14 images which have been mounted and overmatted to 16X20 inch size. I have interleaving between each image and also as a cover for the first image. I include an artists resume and gloves as an aid to the viewer and as an indication that I have placed enough value on my work to hesitate having oil transmitted to the materials.

As an aside, there is an informative site located at http://art-support.com which has a fair amount of information to those who are interested in marketing and selling their work.
