Snoop,

I think what Terry was describing was the fact that all original Shaker emblems had 3 prongs rather than two, so it's apparent that the emblems themselves are reproductions or are missing one pin due to damage. The holes appear correct, but they also appear correct on some of the better reproduction bubbles. One thing I think looks incorrect is the color of the material, originals are not a true white, they have a yellowish cast to them plus it's normally a bit uneven and mottled, it's pretty much impossible to duplicate with paint of any shade. The bubble looks too even so it's likely been completely painted and then over sprayed to make it appear more original, again, hard to say as pictures and lighting can be decieving. As Terry said, if it's a reproduction it's a nicely detailed one, beyond that, can't say from just that pic.

*Pic is an original Paint 71 bubble, a very nice original condition. Good for comparisons
