This is a set of 21 collaboration postcards from Mr. Osomatsu. These postcards feature illustrations related to Mr. Osomatsu, including those from Fes Matsu-san, Character Crepe, Lotte campaigns, stage plays, and manga. The characters featured are the Matsuno sextuplets (Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu), Totoko, Iyami, Hatabou, Dekapan, and Dayoon. While there doesn't appear to be any severe staining or damage, these are vintage paper goods, so there may be some scratches, corner bends, stains, and discoloration due to aging. Please check the images for the general condition. These items have been handled by individuals and stored for a long time, so please refrain from purchasing if you are concerned about minor details. I have a cat. If you have allergies or are concerned, please refrain from purchasing. Instant purchase is welcome. Thank you very much.
