Retro SPUTNIK Hanging Wall Art Silver & Black Color 9” Wide 6” Deep Metal Atomic

Retro SPUTNIK Hanging Wall Art Silver & Black Color 9” W 6” Deep Metal Atomic The black stems or spokes and back of each silver colored half orb are all attracted to a magnet. The orbs are not. I don't know what they are made of. I think it is all a little dusty/dull from being displayed on wall. All seems to be tight and straight and attached as it should. Mid Century Modern look for sure. Jetsons spaceage look that is a definite conversation starter. I don't see a makers mark or where it was made.The metal frames are approx 1" diameter.
