This is old. Made entirely of wood. When did they quit making wooden signs like this?? Probably in the 1940s (educated guess).
The sign measures 18 x 18 inches. With the handle it is about 26 inches tall. The lower portion of the handle is painted orange. The sign is made out of quality 1/4 inch marine grade (no voids on the edges) plywood.
This has a few rubs and scratches from normal use, but not too many. It is in exceptional condition for its age.
The "SLOW" sign looks a little yellowish on my computer, but trust me, it IS an orange color.
