Washington state route 3H highway road sign embossed 1937

Description

16 by 20 inch Washington state highway 3H route sign.  the sign dates to the 1930s or 1940s or so.  it is made to the original 1937 specification that laid out the state highways with a unique suffix-letter system.
condition is as shown in the photos.  sign is white paint on black background, embossed steel.  it lies completely straight and flat, and appears to be a long-ago collector repaint.
lucky winner to receive FedEx shipping, with insurance and signature requirement, at no additional cost beyond the standard shipping amount as seen in the listing.  it makes no sense to leave such a brilliant relic to the whims of the US Postal Service and their package-losing ways.
signs guaranteed old, original, authentic.  bid with confidence.
