I found this one through a google search - it came up on walmart, i.d. as a Better Homes and Gardens Iron Fleur. It's uncannily similar, but not identical and doesn't seem to come in your colors. But maybe this will give you some other ideas for searching. source

I think this is the rug you are looking for: http://www.kirklands.com/product/Rugs-Curtains/Area-Rugs/Navy-and-Cream-Madison-Distressed-Area-Rug-8x10/pc/2288/c/2299/239004.uts Great news is that this 8' x 10' rug in ONLY $269.99 (plus $35.99 shipping) !!! I just got a rug from this company for my livingroom and I LOVE IT! Great quality for the price. Here is another photo of the rug:

You can join the waiting list at Heirloom, but Edmunds has it in stock.

if they are vintage good luck! but here are some suggestions (ive been there for my three vintage bathrooms): Have you been able to pop one off and look at the back and get really lucky to see the manufacturer on the back? You may have to soak it in hot water awhile to get the mortar etc off. then look up the manufacturer on ebay. check out https://matchmytile.com/ and hope you get lucky. go to retrorenovation.com and look up vintage tile and she has many posts about finding vintage tile, including neighbors, is a stash in the basement in a box on a shelf, borrow from behind the toilet, etc.
