The CVP have received an email asking for references to "any publications
using special symbols for variant pieces in running text, for example in
figurine notation". He already has "plenty of examples of
typographically rotated chess symbols as used by fairy chess problemists",
and is seeking specifically variant piece images (if I've read
correctly).
I am unaware of any such; does anyone else here know of any?
