Hiroshige here presents the Yoshiwara pleasure quarters on the single busiest day of the year. However, from the second story of a brothel, the noise and activity seems far away. In the distance, crossing the Asakusa Ricefields, is a procession celebrating the Torinomachi Festival. On this day, the Yoshiwara was open to everyone, including ordinary women. It was also a monbi, one of the special days on which each courtesan was required by tradition to take a customer—or to pay the fee to the brothel owner if she failed. Casually arranged in the foreground are a courtesan’s accouterments. Peeping out from behind the border of a screen are tissue papers delicately known as “paper for the honorable act.”

I understand. Being a layman I didn’t really pay attention to that, as I said, so I’m thankful for the correction.
According to LoC, it is a part of their collection “Visual materials from Donald D. Walker collection”. Although I’m not sure if that’s sufficiently precise - hopefully they have more info on the provenance elsewhere (I would expect the LoC to be pretty on point with that sort of stuff…).
