I found these while cleaning out my parents' house. They seem to be a pencil board from the 1984 "10 Million People Radio Calisthenics Festival Central Tournament", one participation badge, and another participation badge from a different event. I vaguely remember going to a slightly distant athletic field during summer vacation and doing radio calisthenics with a lot of people. The other badge says "Radio Calisthenics Participation Commemoration". I don't know when it's from. If there's anyone collecting these, I'd like to offer them. 〈Pencil Board〉 It was stored in an old plastic bag in a drawer. I don't remember anything about it, but I think I probably used it because it has stains and scratches (Photos ⑦⑧). It seems it was originally white, but it's yellowed from aging (Photo ④). 〈Badges〉 Both were stored haphazardly in the same drawer as the pencil board. Please see photos ⑤⑥⑨⑩ for their condition. ◯10 Million People Radio Calisthenics Festival Participation Commemoration There are many scratches. The plastic part for securing the safety pin on the back is slightly yellowed. ◯Radio Calisthenics Participation Commemoration There are many scratches. The plastic part for securing the safety pin is a light orange color, but it's unclear whether this is due to deterioration or the original color. Please purchase with the understanding that these are used items and have been stored at home for a long time. There are no smokers or pets at either my parents' house or my own. I will protect them with cardboard and cushioning material and take waterproof measures before delivery. I may use recycled materials for packaging. Thank you for your understanding.
