This item was obtained at an auction in 2019. It is a panel with an autograph by Sayoko Hagiwara, who played Princess Yullian (as Ryoko Hoshi) in Ultraman 80 and Dyna Pink (as Rei Tachibana) in Dynaman. According to the description at the time, it was a panel sold to the first 10 people at the Shanghai fan meeting in 2019. The event situation was published on the internet at the time, but it no longer appears even when searched online. The item itself is smaller than the Ultra Hero Memorial. In terms of size, it's larger than B4 and smaller than A3, so I'm not sure what paper standard it is. It might be a Chinese standard, so I've also included a photo of the panel with a ruler on it for confirmation. I looked up Chinese paper standards, and it seems to be almost the same as the (Zheng 8 Kai 270 x 390) standard. The item is a digital printed poster with a gold marker autograph.
