is there is differance in how you see with plastic with ar or high index with ar..would i see the same or would one i would see better?
There's something my brother did for Mother's Day once, that I think would work extremely well in this scenario. Tell your friend's parents and get them in on it. Then, go to her house (make sure she's home). Call her and start talking like normal, just making small talk. Then, in the middle of the conversation, ring her doorbell (if her parents are home, arrange it so they make your friend answer the door). I can guarantee, the reaction will be priceless.
I'd start with Googling 'B-29s', then go to B-29 logos. I'd also try 'artwork on B29's.
