Patent medicine

Ok, so I'm not that great with the calligraphy yet, but I did this piece for a former teacher of mine who in her botany class has never had a student get poison oak from a field trip (and there is plenty to run into on her field trips) so I drew/wrote this for her just for fun. Actual size: 14" x 17"

materials: india ink, small brush, small calligraphy nib.
