I'm going to go out on a limb here and call BULLS@!& on this one. Those look nothing like any PA buck tag I have ever seen. More like the antlerless tag, but not a general license PA tag.

If I'm wrong, I apologize to the hunters who took these great bucks. Yes, it is possible in some areas of PA, we've seen it time and time again. I'm just not sure how valid this pic really is of being a PA harvest.
