Aristophanis Comoediae Vol. I [Oxford Text]
Edited by F. W. Hall and W. M. Geldart. Oxford University Press. Softcover. Condition: Acceptable.
One of the older Oxford texts - no date given, but may be as old as 1890. These are not bound very strongly, and this one is as weak as all the others. But pages clean and of course gives you the industry-standard text.
