Vintage Greg Copeland Signed & Dated Cut Paper Artwork 1970s Retro Style

My parents bought this artwork from the artist in 1971. Original chrome frame. Highly collectible, signed 3-dimensional layered abstract paper cut-outs, framed. The art contains six shape panels in an off-white/creme board framed in a deep silver metal frame. Overall measurement is 14” by 9-1/4" by 1-3/4" deep. Pencil signature in lower right panel and stamped Copeland copyright on the back, along with a #445 C identifier. Listing is for this piece only. I have shown the last photo of a group of three from which this was acquired. Others listed separately.
