Oh thank you for your help. Unfortunately, this is the only article I did find which didn't help much. I have googled and only found one "pisco" and it's a restaurant in San Francisco and I follow them on Instagram.
Thank you so much! It amazes me how everything had to be secured with a patent or else! You are very kind to have spent that much time to research!
Now, if i could only find out if it is worth anything! It still has the gold foil on the neck too!
Cheers!
I have recently opened a small vintage/antique shop and have had these bottles for years in a box. I have googled, Ebayed, Etsy'd and searched Pinterest for both of them so I can price them. I was expecting to find both pretty quick but no luck...and countless bottle pages too! Only good thing...
