The following 2 pics are from a packet of promo stuff I bought on ebay several years ago.  These are 8x10 glossy photos of 2 different guitars.  The first is a left-handed BW, apparently of Bartell manufacture (22 fret neck).  The 2nd pic is the more common right-handed Matsumoku (Japan) version (24 frets).
