This item is a no-value printed matter with the same specifications as a postage stamp. It has perforations on all four sides, and adhesive remains on the back. The size is approximately 3.7cm x approximately 2.7cm, which matches the general standard size of a single Japanese postage stamp. The surface shows the markings "Ministry of Posts and Telecommunications" and "Printing Bureau, Ministry of Finance," indicating that it is a printed matter related to national institutions. However, there is no face value or country name displayed, differing in nature from those issued as regular postage stamps. The design features a motif of monkeys in a light blue color, with multiple monkeys combined to design the Chinese zodiac sign "申" (monkey). It is presumed to have been produced during the late Showa to early Heisei periods under the Ministry of Posts and Telecommunications and Ministry of Finance system. Due to the lack of face value, the presence of official markings, and the postage stamp size, it is possible that this is a trial stamp or a material printed during the printing process. There is no postage stamp with this design. As far as we have investigated, we have not been able to confirm any published examples or market circulation examples that meet the criteria of (Ministry of Posts and Telecommunications marking + Printing Bureau, Ministry of Finance marking / no face value / postage stamp shape). Although the detailed use and production background are unknown, it is considered to be an item with documentary value for collectors interested in postal history, printing history, and trial materials. 【Condition of the Item】 Overall, it is in a clean condition. There is no discoloration, noticeable stains, or peeling of the adhesive. However, due to being stored by an amateur, there are minor paper wrinkles that are almost unnoticeable to the naked eye. Also, there is a tear of about 8mm in the perforation of the upper right corner. Please confirm the condition thoroughly in the photos and make your judgment. 【Size】 Approximately 3.7cm × Approximately 2.7cm 【Notes】 ・This item cannot be used as a postage stamp. ・Due to the unknown details, please consider it for research materials and collection purposes. ・Please refrain from purchasing if you have strong preferences regarding the condition or interpretation. #ErrorStamp #ErrorCoin #TrialStamp #CommemorativeStamp
