In principle, prints can also be roughly dated based on the colors used.

Or you can find an artist's signature, a publisher's logo, or an actor's name.
In this case the artist is Okumura Masanobu, signature "Nihon gakō Okumura Masanobu shōhitsu",
the actor Nakamura Shichisaburō (中村七三郎), and publisher Okumuraya Genroku.
Date around 1720-25.
Which does not mean that the present copy actually comes from this period.
Such prints were recut during the Meiji period and later and also hand-colored like the originals.
Whether original or recut can only prove a very thorough investigation.
