THE PIAZZA Table Knife Hotel Plaza Showa Sterling Silver

This is a set of 6 table knives.
These table knives were part of a set auctioned off when the Hotel Plaza, which operated for 30 years from its opening in 1969 during Osaka's Showa-era bubble economy, closed down.
These are silverware from a historic hotel.

There are slight differences in the engravings depending on the year.
Please see the photos.
Thank you for looking.
