The Golden key Bumper Sticker
Euler's product in relation to the zeta function, as Derbyshire refers to as the "golden key". Euler gave a thorough proof of this relation, which is an important aspect in the Riemann conjecture, relating to the distribution of primes. One of the most beautiful equations in all of maths.

Bumper Sticker
Very disappointed that it's faded in 6 months. Although I have been offered a credit for the sticker, that doesn't include postage, so will be out of pocket if I buy it again and the same thing will likely happen.

The sticker quality is quite good and is exactly what I expected. The colours and font are nice and visible. So will stand out well on my vehicle.
