This question is not about a print but since Kyosai produced many I hope it is alright to post it here.
Attached a painting having a signature reading 惺々暁斎:
Shōshō (Shōjō, Seisei) Kyōsai (Gyōsai), a name used by Kawanabe Kyosai.
The information comes from a site that deals extensively with Kyosai.
One can find there the names he used, examples of his signatures, and of is seals:

From that the signature in this painting looks OK, but I could not find the seal, nor was I able to read it. An educated guess would be welcome too.
