The left one is a strongly Base embossed Chicago Insulating Co piece with millions of micro bubbles that make it look almost like Jade blue. Really neat. I paid 500.00 for it about 10 years ago. It has 3 dots on the side & I would call it VNM exept for the minor dome cooling crack & the horizontal cooling crack in the middle of the diamond section that is characteristic to manufacture with these. This is a solid museum style piece! I will sell it for 450.00. The middle piece is a yellow green "B", with some nice bubbles & the rare #15 backwards dome mold. Looks mint to me. It can be yours for 20.00. The right one is a bright Hemi blue CD 202, Hemingray 53 w/small sharp drips! This is a real hard piece to find in NM & is loaded with lots of micro bubbles. The best you will probably ever see. This one is sold. Sorry. The others are still available!
