Sofu Teshigahara

I have come across, 2 folders of Sofu's Ikebana and sculpture photos. Each folder has 16 photos that are mounted on card stock and have the description of the item in both english and japanese printed on the bottom of the card stock. I bought them at a  sale of a japanese lady who was down sizing to a condo. I was trying to find out if they have any value, the folder or the paper that is folded around them has a sticker in english and japanese, the date is 1968.  I think they are a catalog?
