Dup - I checked the box the bouncing bomb came in, and found that they had used the original wrapper from your box as padding.
There was a postage stamp on it, but it looked like it had gotten wet, and was competely smeared. I can't read the date or postmark. It has "Postage Due" and "$5.35" written over it in pen (hand written). The return address was:
Richard Petty
1028 E. 22nd St.
Kannapolis, NC 28083
It was wrapped in shiny silver paper. It has a large Priority Mail sticker, and a DC sticker on it, # 0304 3490 0002 7764 2111
As I said, my address on it was completely correct.
I don't know if this is worth anything to you, but send it along.
