Within researching for posters,my 18th century research is revolved around an old printing method called “Wood block printing.”
This poster was designed and printed by Kunichika Toyohara in 1890,using the method of wood block printing, this was used to advertise a Kabuki play in Japan (the play is called Onoe Kikugoro V as Akashi no Naruzo in the play Shima Chidori Tsuki no Shiranami) . All of the names above are performers of the play.
The method wood block printing was dated in the Edo period (1603-1868). The method was done by having the text or image drawn onto paper then glued faced-down onto a plank of wood, the wood would then get carved/chiseled onto based on the outline of the text/image. After the block would be layered with ink and then pressed onto a new sheet of paper.
For my 20th century poster I have found this poster advertising to travel to Japan by steamship companies in Japan. This poster can also be found in a book called Miwaku no Funatabi. (source)
This poster appealed to me because the style has a bit of a vintage feel to it and looks very life-like.
