Gekidan Shiki Cats 30th Anniversary Clear File, Yokohama Performance Flyer, Sticker, Additional Flyer

This is likely a 30th-anniversary clear file from the 2013 Shizuoka performance.
It was stored outside of its original packaging.

The items from the 4th to the 9th photos are flyers and commemorative postcards from the Yokohama performance. The postcards have some fading.

I found some different flyers, so I'm including 3 more. Please check photos 9-12. The pink one has a crease on the right edge. Upon closer inspection, there are small creases and wrinkles throughout.

I'm not sure when the stickers are from. Two have been used.

The clear file is unused, but please understand that the other items have been stored for a long time and may have some damage before purchasing.
