I bought two reclaimed wood shelves from Etsy, intending to use them as a pair, but we ended up preferring the look of using just one.  Shelf is a floating shelf that mounts on a hidden steel bracket.  Attached are pictures of the shelf we mounted so you can see it in use; the one for sale is substantially similar but slightly different due to the nature of reclaimed wood.  Dimensions: 36" x 6" x 1.75" inches.  Finish: Dark Brown.  Here is the seller from which we purchased the shelves with more details (please note the photos show a different finish; the one for sale is dark brown).  https://www.etsy.com/listing/267805814/heavy-duty-reclaimed-wood-floating

If you needed more than one, you could always buy this one at a discount and order more in a dark brown finish direct from the seller.  

Cost $148 new including shipping; we're asking $125.   Cash only; pick up in Highland Park.
