Increasing Traffic on Madrid's Route 66(a)

Today's Trademark Official Gazette includes 22 more Section 66(a) applications published for opposition. These Madrid applications are not segregated from the non-Madrid. I found them by opening the .pdf file in Adobe Acrobat Reader 6.0, and then searching for the term "SN 79" (since all Section 66(a) applications have a Serial Number beginning with "79").

To me, the most interesting of the 22 appears at page 328, an application to register what appears to be a stylized letter "P" for certain clothing items. Why does that mark remind me of a certain baseball team in Philadelphia?
