The problem/bonus of having a sliding timescale is that you get to reinvent your original team from time to time...much like the X-Men First Class Team Button! Just look at how the original members are rendered in a slightly newer style! Pretty sweet!

Measuring 1.25 inches in diameter, the X-Men First Class Team Button has Cyclops, Jean Grey, Beast, Angel, and Ice Man! Now if only we can get Mimic in there then we would be really set. Oh well! The X-Men First Class Team Button is still one rocking button!
