Via my facebook feed, I discover that the smallest pink tower cube is available on amazon.com here, for $1.50. With a little more digging, a wide range of items under the heading “Montessori materials” can be found, some familiar from your albums, some perhaps less so. Obviously this goes to the question of authenticity, but that’s not really the point—the point is exposure, and Montessori’s dispersion into the public consciousness. Searching “Montessori” on Amazon (including books, materials, toys, and everything else) gives 5,410 results. By way of comparison: Waldorf—8,467. Reggio Emilia—1,793.
