"The subscribers thankful for past favors and desirous for a continuance of the same would respectfully inform their old customers, and the public generally, that they have now on hand and for sale a large and general assortment of neat and fashionable hats of their own manufacture, consisting of black and drab, fine and common fur, all of which they are determined to sell wholesale or retail, very low for cash or approved produce. They particularly recommend to the public a stock of fine white Beaver hats of a superior quality, which they design for this spring market, with some very fine other hats of the best quality. Those wishing to purchase are respectfully invited to call and examine their hats and prices. From their experience in the manufacturing of hats and care taken by them in the purchase of good materials, they flatter themselves that they will be able to give general satisfaction to all who may favor them with their custom. No pains will be spared on their part in rendering their hats as good, as say, others manufactured elsewhere. And they pledge themselves to sell as cheap, as hats of the same quality, can be purchased in the western country; and much cheaper than hats have been sold in this market."
