Vintage Cobalt Blue Oblong Wavy Bottle.

I bought this Vintage Handmade Cobalt Blue Bottle as part of my "Blue Glass" Collecting Phase. It was a great piece as part of my decorative bottles collection. It has the following makings in the bottom; A, 20cl, 3, 60mm, and hard to possible recognize brand marking (animal sitting above a triangle?).
Condition: Excellent.
PLEASE NOTE: Thank you for looking at my post. I check my emails 1-2 times daily, but may be delayed due to my disabilities, which require me to visit hospital. The exchange must be in-person, with cash, at pre-arranged pick-up at my location. If your out of the area, please have family, friend, or arrange courier service to pick-up on your behalf. If you're not happy with the $ I'm selling at, make a reasonable offer, or check back after I renew/repost the ad next cycle. I'll always lower $ in increments until it sells. I appraise and price based on comparable items and conditions online, and sell just a little bit lower to make attractive. If I post as "RARE", then I know of no other available for sale. If you think it's valuable, buy now, before someone else does! Good Luck on your Treasure Hunt. Hope to hear from you soon.
