Its funny how in the past when I looked at plane adds I never really noticed any of the planes in the background because they were just plane "planes".
But once you get into a unique bird like the skymaster, you seem to tend to notice things.....I was looking at this add:

And as you look through the pictures, you can see a skymaster (looks to be a really nice one) on the ramp, and several parted out ones in the background.
Now if those were clapped out pipers, I never would have even taken notice of them.
