This weekend’s art exhibit at STUDIO WALSH will benefit the Good Samaritan School of Haiti and provide resources for children in the most at-risk areas of that nation. Vanessa Craan’s portraits are colorful, vibrant and overflowing with energy; Philippe Attie’s realistic work is infused with lightness and creates a meditative sense of calm; Thierry Barthole’s charcoal drawings bring his subjects to life with technical perfection. All three will be at this evening’s and tomorrow’s opening receptions. After these dates, the exhibit can only be seen by appointment.
