Designing posters, calendars, and postcards with your shops own art work allows your marketing tool to double by promoting your outlet as well as the art in your outlet. I belong to a cooperative nonprofit gallery and that is how we create all of our marketing tools.
Our cooperative also invites calls for contributions to local fundraisers. I have personally contributed my own art to silent auctions locally hoping to expand my viewing audience. Since I have done this I now sell more art at the gallery than I do online.
