1970s Topps on the back was in a different typeface. The Burger King set featured 22 cards plus a checklist card. Several cards reflected players changing teams, most notably Pete Rose (Phillies) and Tommy John (Yankees).

Size consistency and size extensivity Size consistency and size extensivity In quantum chemistry, size consistency and size extensivity are concepts relating to how the behaviour of quantum chemistry calculations changes with size. Size consistency (or strict separability) is a property that guarantees the consistency of the energy behaviour when interaction between the involved molecular system is nullified (for example, by distance). Size-extensivity, introduced by Bartlett, is a more mathematically formal characteristic which refers to the correct (linear) scaling of a method with the number of electrons. Let A and B be two non-interacting systems. If a given theory for the evaluation of the energy is
