どうだ明るくなったろう 明るくなったろう
[i]"Dou da, akaruku nattarou"[/i] ("There, that's brighter, isn't it?") is a dialog caption from a satirical cartoon from about 1928.

While the man in the cartoon is unnamed, he's apparently modeled after "Tadasaburō Yamamoto":https://ja.wikipedia.org/wiki/山本唯三郎, a businessman from humble roots who grew very successful in the late 19th/early 20th century.  He was known for flaunting his enormous wealth.  

One night, Yamamoto was leaving after an extravagant meal at a restaurant in Hakodate, when he saw a geisha searching around in the foyer for her shoes, having trouble because of the darkness.  He therefore pulled out a ¥100 bill (now worth about ¥1 million, allowing for inflation) and lit it to brighten the area.  The incident became famous as an anecdote of [i]nouveau riche[/i] behavior.

Years later, an artist named Kunibo Wada heard of the incident and drew a satirical cartoon depicting the situation, entitled ""The Age of Nouveau Riche Splendor":[https://kyuman.art/themes/main/facility/images/img_works_10.jpg]".  The cartoon appears in current Japanese history textbooks and so has some slight fame among the public.  It had gained a similar level of popularity as a motif for ASCII art and gag images.
