* NFT Museum of Archeology
*
* Do you got what it takes to become the ultimate NFT archeologist?
* Get your hat and your whip to find the rarest, yet undiscovered NFT!
*
* We think science should be accessible for everyone.
* Therefore this is a free mint, contains no royalties and you may trade it everywhere.
* On top of that, lesser known collections might get some more awareness.
*
* In order to dig for specimens, you'll need to mint.
* There are 3 rarity levels "Common", "Rare" and "Super Rare".
* The more forgotten a specimen, the more rare it is.
*
* Max. 2 mints per wallet.
* Owners of Rarity Garden Genesis Unicorns get a boost and may mint the equivalent
* of the amount of Unicorns they own.
*
* Initial supply is set at 1111. With time progressing and sufficient
* community demand, there might be more to dig. The absolute max. will be 10,000.
*
* Reveal is instant.
