john williams water house, cleopatra, 1887 (a pre raphaelite)
let's go back to the 2/25 lecture.
there's plenty to talk about: chromolitography, yellow journalism, the presentation of fashion in magazines, photojournalism, natural science illustration, pictorialism, victorian design, the pre raphaelites and their aesthetics, star designers like william morris, dana gibson, privat livemont, thomas nast, randolph caldecott, etc.
an observation: in your comment try to dig deeper, i.e., be less casual and more deliberate. use wikipedia if needed to amplify your ideas. there is plenty in here to write 150 words.
