Thanks to Greg W. for this heads up. Barnes and Noble stores currently have Vespa end cap displays with journals, pens, bags, magnets, notecards, and even a cute fender headlight alarm clock! Only the notecards seem to be available on their site though so a store visit is a must.
It looks like not all B&N stores have the Vespa merchandise. I was in the B&N in the Lloyd Center Mall in Portland, Oregon.
