Wellspring Publishing (booth on left) publishes and distributes a variety of items. I think their booth actually wrapped around to the other side of the aisle. They have books, coloring books, bookmarks, stickers, calendars, cards, matted prints...just lots of things.
The booth on the right is Stevenson's Genealogy Center. They have every genealogy item that you can think of, and several more that you would not have thought you needed (but, of course, you do)--binders, sheets and forms, how-to books, kits, software. They also publish family histories. Cool.
