Rob,
Yes, and that is another good example of the occasional inconsistency of this classification system. Coupon Type 1's are significantly different artistically than Type 2's and Type 3's yet are all classified as T213's simply because of the Coupon brand. Cracker Jacks were distributed and advertised differently between 1914 and 1915 sets yet are both E145's simply because of the Cracker Jack brand. However, you then have a single set like T206 that is a conglomeration of many different brands and series over multiple years.

I have a TREMENDOUS amount of respect and appreciation for Burdick's work. I think his system is well-designed and user friendly in many ways. However, the fact remains that it is an arbitrary system created by a human being and as such, contains many inconsistencies. I think there is nothing wrong with continuing to update and add to Burdick's generally outstanding work as new information and theories emerge over the decades.
