Vintage Mid century Art

These are a pair of vintage mid-century modern (MCM) gravel art panels, likely from the 1960s. The art style is also known as pebble art or crushed stone art and was a popular do-it-yourself (DIY) craft during that era, often sold as kits.
Key Details
Art Style: The pieces are made using a technique that incorporates small stones, pebbles, crushed glass, glitter, sequins, and sometimes beads and molded plastic, glued onto a background board.
Subject: The set typically features two birds: a peacock and an egret (or crane), as seen in the image.
Era: This type of art is strongly associated with the 1960s and 1970s mid-century modern aesthetic.
Origin: Many examples, including similar sets, were created from kits and made by individuals at home, which means they are not typically attributed to a single famous artist, although some commercial versions by companies like Greg Copeland or Jenev studio exist.
