It is signed Ichitosai (utahawa Toyokuni 2nd). Height is 37 1/2 inches, including frame and the width is 26 1/2 inches.
The woodblock print or ukiyo-e you bring in is original designed by Utagawa Toyokuni II or Toyoshige. He continued the work of his (adoptive) father with the same name ( Utagawa Toyokuni I ). I believe your print is a later reprint and not printed in his live. It is definitely an antique one made, I believe, in second half 19th century. Many prints were made later so it is quite common to have a later version. Colors of the old one's are little more faded and are different. The metropolitan museum of art has a nice collection. If you use the search button and search for him you find some nice original one's. If you would like to sell I recommend an auction house with a prescription to an online platform like Invaluable, live-auctioneers or other. That way you are sure there is a good international audience for it.
