One can only surmise that this tie (like the Burro, Sombrero and Hay Wagon set) may have come in a variety of color combinations, the others of which we can only imagine.
This tie has a seller's label which reads:
Bishop'sOn the reverse of the label is another label, loosely stitched to it, which reads at the bottom:
UNION MADE NECKWEAR.There is a union symbol, and more wording at the top, which is too faded to make out. I provide a close-up of the label here, for anyone who might be able to read more of it than I can.
