We got our hands on a stash of mid century scientific diagrams from the archives of the Griffith Observatory, Los Angeles. Figure 5, pictured here, charts "Comparative (H2S + SO2)." Don't ask us to explain what on earth that means (something to do with comparing sulfur dioxide and hydrogen sulfide), but we sure think it makes for a neat print.
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 condition.
