Tulip bar stools brand identification  

Yes, that's the pair I saw.  We don't get into value opinions here.  Your best gauge of value is what similar  ones have sold for, which you can find on sites like Ebay, Liveauctioneers, and Chairish.  This set sold on Chairish for a high price by a New Jersey dealer.  If you're not in a hurry you can always list them high and drop the price every week or so until they sell.     

A decent general guideline is to leave in any event 6 creeps between each stool. In the event that your stools turn or have arms, you ought to permit at any rate 8 or 10 creeps between them.

@Sheilaj So I happened to be in Houston today and decided to stop by Metro Retro. Amazing place if you’re ever in the area. Anyway, I noticed they had this set that looked to be the same design as yours and took a picture of one  of the tags. Contemporary Shells. I guess they changed the design at some point.
