I checked my 1959 Kingsport City Directory and saw that this location, on the corner of East Market and Cherokee Streets (245 East Market Street) , was then W.B. Greene’s Bargain Annex (used furniture). Nick’s Western Shop, which also specialized in square dancing regalia, was owned by Nick Drakos. I can anecdotally track the business back to around 1960 or so, but I don’t have a firm opening date. I think I took this in the mid-90s, when I learned that Nick’s was going out of business. Corrections and additions appreciated!

I’ll get you more info, that’s my grandfathers place.
Early 50s was shoe shine and hat blocking then converted to square dance western shop.
Closed/retired successfully in 1980 maybe 1981.
Email me back and I’ll supply full details from my father.
Any information you’d like to pass along, I’ll post on this site on this post. I don’t want these parts of our history to be forgotten. Many thanks!
