This site is not set up to list the art fairs, you must have been on my other site, ArtFairCalendar.com- a site aimed at visitors to art fairs. This site is planned for artists to get together. But (I'm sure you are surprised to find) I accept ads on both sites, as well as on my newsletters, very reasonably priced. What did you have in mind? The cool gizmo you and Jan developed?
