Your pottery pieces appear to be Southwestern-style Native American-inspired art, likely made in the late 20th century by a regional artisan—possibly “Melissa D” and “AR.”
Left piece: A wedding vase—a traditional Native American form symbolizing unity. The initials “AR” suggest a regional artist, possibly from Arizona or New Mexico.
Right piece: A small jar or olla with similar roadrunner and desert imagery. The base is signed “Melissa D” with a stylized mark.
The textured clay and painted roadrunners are common in Southwestern tourist art from the 1970s–1990s.
They are in excellent condition. Selling as a set.
