First, these images are not mine (there, I feel better now) I am wondering if there was a rhyme or reason to these covers. Of the two original Macs I have, each has one. The oldest has the smaller icon near the top of the cover. The other is what I think I can call the more common one. These covers can easily get misplaced, replaced, etc. So I don't know if the ones on my Macs are original to the machines.

Wondering if the smaller icon without boarder was used on earlier Macs and if the one with boarder on later units. Or if its just a mixed bag. I know, silly question. But when it comes to getting an original Mac back to original as possible, it counts.
