Master Glass Company Marbles by George Sourlis, Paperback | Indigo Chapters

I have written this book because information on this company and its production items is sparse and very confusing. The confusion arises from the fact that its marbles appear in boxes and bags of two other major companies: Akro Agate Company and Master Marble Company. I am hoping to clear it up, to provide information to distinguish its items from those of the other two, and to provide reliable pricing for Master Class Company products. Some pricing is also included for Master Marble Company. | Master Glass Company Marbles by George Sourlis, Paperback | Indigo Chapters
