Opera.
Title information on a label pasted on p. [1] of cover; "Ernani" and "Verdi" are entered by hand; the rest is printed.
From an early edition of the parts; engraved.
Each of the numbers has its own caption title, separate pagination, and pl. no.
The pl. no. (and the Ricordi Libroni) suggest an engraving date of 1844, but a publisher's note printed at the bottom of p. 2 refers to section 8 "della Sovrana Patente 19 ottobre 1846."
Library's copy lacks p. [3]-[4] of cover.
