Old and used book fair at Kanda Jimbo-cho bookshop street

I went to the bookshops street today and came to know that old and used book fair starts from the day after tomorrow, Friday.
Workers were busy to fabricate bookshelves for pavement stalls.
I don't think there are many foreign book shops on the street, but at least there are three shops. One of them, Ohno bookshop is pictured.
