"The Spider's Thread Mechanism" by Juichi Sawazaki / Kei Kuribayashi Price: 1,200 yen #JuichiSawazaki #KeiKuribayashi #Book #Insects #Spiders #Spiders #InsectEcology This is a considerably old book, and there is soiling and yellowing due to age. There is no cover. The parts with graffiti have been covered with stickers. (Please refer to the photos.) The photos are also works by Kei Kuribayashi, and I think it is a rare item.
