Pennsylvania inspection sticker

Hi can anyone help with identifying the year on this PA inspection sticker  I know the 5 indicates it expired on the last day of the 5th month but the first box is empty  which I'm assuming should have the year in it.
I'm trying to find out when it was last on the road the only other thing I have found was the battery was dated 15/7/09

Does it resemble this? 

I'm guessing the color of the sticker represents the year.  Here is a chart that shows the color for each year.

It seems likely that the car and motorcycle stickers would use the same colors?
