I noticed in another thread that someone put a T206 (-2) together in six months. Even collecting every card (excluding backs) all you need is money to make it happen.

How could this set be called a "monster" if it can be assembled so quickly? Of course, I do understand part of the reason is because of how many cards are in the set.

I'm not trying to minimize the accomplishment for the collectors going after the set (I may even try it myself someday). But what sets are really a monster? What sets would take many years or even decades to complete?

N172 - N175, actually all of the sets from the 1800's?
