Hi guys...Just took a stamp from
http://flyspecker.comBTW, this is a great site for constant, go there and enjoy...

The constant variety shown on this stamp was discovered by Earl Noss and features what appears to be some kind of plate scratch or scuff that begins at the rooftop of the building just above the right wing of the plane and continues downward across the wing and onto the right engine
...discovered by Earl Noss
LOOK AT THE MIDDLE OF THE CIRCLE.


There are also more oddities (and with lots, and lots of other stamps) I nick named this CONSTANT ODDITIES for lack of a better term.
LOOK AT THE SMOKE STACK IN THE CIRCLE..ALL OTHER PARTS OF THE STAMP ARE COVERED BY THE AIR STREAM FROM THE PLANE..EXCEPT THIS ONE..IT IS ON THE OTHER SIDE OF THE STREAM..

THE EDGING OF THE PLANE WING IS OVER TOP OF THE AIR STREAM THAT CAUSED IT TO DISTORT..THE STREAM SHOULD BE OVER TOP OF THE WING EDGE.

LAST ONE IS THE COCKPIT WINDOWS..THE LEFT SIDE OF THE PLANE HAS WINDOWS..THE RIGHT SIDE HAS NONE..?

Have fun finding these..I have lots more of the same thing...enjoy
