It is available in 4-ply (14 pt.) or 6-ply (20 pt.), and available in colors and Uncoated White. Railroad Board was developed in the late 1800s, and used in train stations for identification purposes.

Colored Poster Board  The color is coated on both sides of the white sheet with a durable and smooth coating, so it is more fade-resistant than Railroad Board and does not bleed when moistened.
