SOLD - 1960s Scientific Diagram - Singularity/ Event Horizon/ Black Hole Mounted in Window Mat

We got our hands on a stash of mid century scientific diagrams from the archives of the Griffith Observatory, Los Angeles. This one's a vintage slide transparency has text that reads "SINGULARITY / OUR UNIVERSE / OTHER UNIVERSE / TIME SPACE / EVENT HORIZON." We believe it illustrates the occurrence of a black hole. Its pretty fantastic.

Newly mounted in a custom acid-free overlay window mat and protective plastic sleeve. The print is c. 1960s vintage. It's in very good vintage condition; the transparency printing shows mild wear as pictured.

Dimensions:
Image size- 10.5" x 8"
