To answer a couple points raised by budler.
If a set is sponsored by a food company, it goes under the normal category for that type of set (team issue, minors, etc.). It is only a food issue if you had to purchase food to get it, or it was only available at a dining or grocery establishment.
Single cards are the base set, with panels as a parallel if, and only if, that was the sole means of distribution. (The only exception we've had so far is when those "panels" are actually 2.5 X 3.5 cards themselves.)
Both of these points are directly from Admin.
