Chalk or "blackboard art" have some big names currently, but I really like the work of local artist Catherine Owens. Many artists do the lettering well but Catherine kills it w/ the surrounds; art nouveau in this case. This menu is up at Backbar in Union Square, Somerville. It took her about 35 hours over 3 days she says. Video of the process below -cool that she left in her erasures and retries... DM me if you would like her contact details for work.
