Since the early 1950's, companies such as Greensteel, Nelson Adams, Alliance,
AKI, and Carolina Chalkboard have evolved into the American side of today's Polyvision.
Polyvision has created over One Hundred and Twenty-three Million square feet
of writing since moving from high maintenance chalkboards of the past to the multi-purpose
ceramic colored writing surfaces of today.
The Polyvision line ranges from Mini Eases for use by Elementary School children
to the Track Wall System and Writing Wall Systems shown above.
