The numbering system was devised by the late Don Liberko, who worked extensively on cataloging the different styles. It has been enhanced to include newer versions and versions not included in his cataloging.

We are currently working with transfer experts to verify/correct/populate transfer style dates. Currently they are our best estimates. Once solid dates are established (and new styles discovered), the style numbers may change to reflect the correct chronology.
