Banner stamp error or irregularity

It may also be significant that Alx has stated: "looks like the toggle has a different color cast"

Notice that along the top edge of the logo there is a double pointed torpedo shape (I do not know what else to call it). Notice the distance from the left edge of the logo to the left tip of the torpedo. Now notice the distance from the right tip of the torpedo to the right edge of the logo. See how these two distances, which should match simply do not match? Unless this is a matter of photographic perspective, then these differing distances can not be accounted for by the use of a roll die. The distances in the factory roll die itself would have been perfect as shown in the example provided by Marc.

However, it would be interesting to look at the condition of these lines under higher magnification. Notice how jagged the top outline of the logo appears to be? This is exactly what one would expect if a Pantograph had been used to create this logo rather than a factory roll die.

Quite a mystery.
