Crypto Masks is a collection of pixelated face masks. They were made to commemorate a global historic event, the Covid-19 pandemic, that so far took the lives of over five million people. In the old day's such an event would be written in stone so that it could stand the test of time, and bear witness by future generations. Today we can write witness of a global event on millions of computers. And what better way to do so than using blockchain technology. A few years from now, the pandemic will be over, but the statement of what happened at the start of 21 century will stay witnessed for eons to come. P.S. There are 11111 similar but unique Crypto Masks in many colors, but there's only one Rainbow.
