Many years ago I purchased a set of rubber stamps with the Regina logos
and letters of the Regina font to be used for printing on the discs.
I have not attempted to use them. These are not 100-year-old stamps but
nice flexible rubber, quite suitable for printing and never have been
inked.  Someone went to a lot of work to do an exact reproduction of
these logos.  I have a pile of discs and have not inked them up and
I wonder if they will work satisfactorily?  If so, if you have cleaned
discs with no printing, this may be the answer...
