In the first image, you have to look closely to see that the black lines which form the triangular design, somewhat reminiscent of suspension bridge cables, continue with another set down in the bottom forest green section, parallel to the large blank orange triangle.
And the primary reason for the second scan was to show the most interesting aspect of the design, which is how the lines all converge, and then diverge once again in the opposite direction, further up the tie.
This tie has both the sellers and manufacturer's labels intact. The first reads:
WILSON'S W SHIRT SHOP INC.
535 Broadway at Alder
Portland, Oregon
while the second is the familiar:
Fashion Craft
Cravats
with the letters SN enclosed in a diamond shape.
On the reverse we find the usual:
Resilient
Construction
