Thank you very much for your post, Orion-san.
From what you and kuroimori-san wrote it seems then that this particular banzuke was an offer to someone from Michinoku Oyakata, right? I have no intention of selling this banzuke, since banzukes are one of my collection ozumo items, but does that mean that this particular banzuke has added value, as compared to the regular banzukes? Would this be considered a special collector's item?
Many thanks in advance,
Terunoumi
