A tune for a token : tokens used to play mechanical music machines
Q. David Bowers (Author)
"In his 1975 work, Dave cataloged approximately 190 tokens and commented 'I believe that the present listing is just the tip of the iceberg and that many more varieties remain to be discovered,' How right he was; the book you are holding [catalogs] more than three times that number, and this is even more impressive in view of the fact that the original catalog listed advertising tokens, issued by companies that sold player pianos; they are not included in this edition." -- Foreword
