Engraving is done on vintage Tru Flect Copper plated mirror. I can't find anything on the artist or artwork. It looks like it might be sandblasted. Engraved by Ron Boyd. Appears to be mid century piece. Measures approximately 20" long and 16" wide. Main plane in front with 3 other plans in formation above.
Signature looks fuzzy but is not. It is only the reflection of itself.
