Mike -- what is your definition of a true variation ? Would it include the 58 Herrer, the 57 Bakep, the 52 Campos Black Star, the 67 Moeller white streak, the 61 Fairly green in the ball on the back ?
Do you know one when you see one or rely on someone else to tell you what are true variations
. No offense intended , who would have thought the 61 Fairly would be a recognized variation. Would the Herrer and Bakep make the cut post Internet ? Should there be a hobby accepted definition of a variation ? Collect what you like . I do. Hobby recognition does drive value, but is the 61 Fairly a print dot in your view ?
