New Belgium Brewing has built an digital portfolio submission page as a low-effort way for artists to share their work with their creative team. Details and more information on their website: http://www.newbelgium.com/
Artists/makers who have an interest in sharing their work with New Belgium Brewing should fill in the online form provided. While New Belgium Brewing already has a fairly robust list of artists and makers, there’s always a chance they don’t know someone who they should. They plan to keep this submission process active at least through when they open as they may want to use it as a resource later. Additional info is available in the FAQs at the bottom of the page linked above.
