The original Baby Trekker baby carrier in faded denim. I suppose you would call it vintage. I bought it second hand in 2001 and carried my daughter around in it for many happy months - I tried lots different slings and this was hands down the most comfortable. Been holding onto it for sentimental reasons but time to let go. I would love it if someone could get some use from it.
