Hoaxes & Cons

"Viewers around a glass case, engraving of 1855" by Whitney & Jocelyn, engravers — https://commons.wikimedia.org/wiki/File:Mermaid_viewers_American_Museum.jpg — Public domain — Public domain in the US (published 1855) and in the EU (signed Whitney & Jocelyn Sc.; death dates not checked, treated as expired by inference from the 1855 publication, since protection would need an engraver working in 1855 to have died after 1955)

"Scoperte fatte nella luna dal Sigr. Herschell" by Salvatore Fergola — https://commons.wikimedia.org/wiki/File:Scoperte_fatte_nella_luna_dal_Sigr._Herschell_LCCN2012646034.jpg — Public domain — Public domain in the US (published 1835) and in the EU (Salvatore Fergola died 1874, life+70); modified: cropped to the winged figure and two animals, removing the title, the paper edge and nearly all of the moon scene above (a strip of its lower edge remains at the top)
