I have received my Gardner book. I haven't read it yet, but i can report that the illustrations, while hardly stellar, are reproduced fairly well for a book of this price. The photos are not all that clear or telling. The drawings are much clearer, though they are not expertly drawn. Once i have time to read it i will gladly report any obvious errors i find.
I must agree with Alan and Ganja that the Solyom is one of the very best i have encountered and a must have for any keris enthusiast.
