Railroad Board (like Poster Board)
Railroad Board is often referred to as poster board, but is a little different. It is smoother and more like a bristol board. Railroad board is the same color trough and on both sides. It accepts marker, tempera paint and acrylic paint very well and is great for posters, signs and tags.
The railroad board we have available is 4-ply (~ .017" / .43 mm) and measures 22" X 28" (56 cm × 71 cm). Sheets are sold individually.
