Sculpture show

The Boston Sculptors Gallery, 486 Harrison Ave., is displaying works by Fafnir Adamites and John Christian Anderson, now to July 23.

Adamites’ work is “Holding Remnants,” large-scale paper sculptures that act as monuments and reminders of objects, people and actions that came before.

In “My Inheritance,” Anderson uses both scavenged material and handcrafted components to create his work. The resulting sculptures present themselves as facsimiles and evoke an ominous dark element along with a humorous sensibility. The exhibition title references a future in which art will be created in a world of limited and ever-dwindling resources.

Gallery hours are noon to 6 p.m. on Wednesdays through Sundays.

Further information can be found at www.bostonsculptors.com or by calling 617-482-7781.
