All are welcome to celebrate Juneteenth — an African American celebration of when all slaves were freed — on Saturday, June 14, at the Oak Bluffs School from 2 to 4 p.m.

Although the Emancipation Proclamation was signed in 1863, the slaves in Texas were not notified of their freedom for another two years. This event is celebrated in many communities, though not yet a national holiday.

The guest speaker is Robert Tankard. The Martha’s Vineyard NAACP’s new choir will be conducted by Lawrence Watson, Berklee School of Music professor, who also will sing.

Students are invited to contribute to an art show titled Freedom. This show is open to kindergarten through twelfth-grade students; they are asked to draw a picture of what freedom means to them. The art will be judged by Featherstone Center for the Arts executive director Francine Kelley and Dragonfly Gallery director Holly Alaimo. There will be three categories: kindergarten to fourth grade; fifth through eighth grade; and ninth through twelfth grade.

The winners will be interviewed on MVTV for shows hosted by Jim Powell and Bob Tankard.

A silent auction will offer items such as a seasonal weekend at a family camp in New Hampshire that can sleep 20 to 30 people as well as a deep-sea fishing trip for four.

The co-sponsors are the Martha’s Vineyard NAACP and the Island Diversity Council, request a $5 donation per person at the door.
