Steinway keytops

[Mark Graham]

We have a Steinway D from the 1980's that is commonly referred to as "the
one with ivory keys". But I have always thought that they can't be ivory.
They are ivory-colored, and have a grain pattern. But the pattern seems to
repeat exactly, which is unlikely, and the keytops are of one piece, not
separate front rectangles and back rectangles.

Is this simulated ivory? What do we have here? They feel great. They are
the factory original material.
