Briefly about the Manufacturer
Copernicus Toys is an independent American educational toy maker based in Charlottesville, Virginia.
We've always & forever been a family owned & operated business! Long, long ago two galactic travelers named Ellen & Harris gathered & developed artifacts of science & nature to sell from their home world, Copernicus Toys. After a while, as all beings do, they retired & downloaded the Copernican System to a new duo, Avi & Peggy.
This new duo & their two tiny daughters fearlessly took on the adventure. Avi had been busy developing keen design sense at what earthlings call a job. Peggy honed her education skills & sense of whimsy far & wide. We carry on to this day making new toys while spending plenty of time with our, now slightly larger, daughters in our own little solar system.
