I've seen it before also. It is a picture of Homer Simpson driving his
car down the road, admiring fluffy clouds overhead.

Steve,

Hello,

The suspect is completely flat and smooth to touch. An interesting
observation is that though it appear at the same location for all the
10pcs of board, the size of the image tend to get smaller and smaller if
the boards are arranged starting with the largest image. It can't be
soda strawing as it is not on trace. It can't be pink ring as it is not
around hole. What can it be? What is the likely cause?

Will ask Steve to put it up. Kindly take a look. Your opinion is greatly
appreciated.

Regards,
Wee Mei
