The '05' shape is one of the most iconic (perhaps the most iconic) of Peterson's shapes. It's easy to see why-- it's not such a classically English shape that it's like all the other, for example, Billiards out there. It's an old, old Peterson shape, but one that has remained largely unique to them (or, at least, is perfectly recognizable as Peterson's shape when others make it). It's presented here as part of Peterson's Christmas series, which complements the spirit of the holiday season with seasonally festive metal ring, complimented by stripes of red and green.
