Original Document, not a reproduction 

1852 "Kaiserliche Akademie de Wissenschaften" (Austrian Academy of Sciences) award certificate to John Herschel as "Sir John Frederick William Herschel Baronet."

"zum Ehrennitgliede in deer mathematisch naturwissenschaftlichen classe erwahlt seine Kaiserliche Konigliche Apostolische Majestat Haben dies Wahl mit Allerhochster Entschliessung vom 19 Juni 1849 Allergnadigst zu bestatigen geruhet Wien a 1852"

Rough Transaltion: "His Imperial Royal Apostolic Majesty has been elected an honorary member of the mathematical and scientific class Have graciously confirmed this election with the highest resolution of 19 June 1849 Vienna in 1852."

Extremely high paper quality.  Measures roughly 23" x 18"

Superior condition - folded into 6th and stored since 1852.  One diagonal tear at the right about 1".

Perhaps this is why this one is NOT signed, but it does have the raised, embossed seal of the "Kaiserliche Konigliche Apostolische" for the Austrian Academy of Sciences.

An amazing opportunity for the Herschel collector.
