All I have to say about these 3 is, WOW!! I found these at an indoor flea market just north of Birmingham, Alabama. I bought these 3 along with about 10 others for $1 a piece. All of them were CAKED with dirt and soot. The colors were not apparent when I bought them, I just grabbed them because of them being dated. After a nice scrubbing with a brillo pad, this was what was uncovered!!

The one on the left is a nice darker green FULL of bubbles. The middle one is almost just as bubbly, and seems to be a hemi-blue. The one on the right is more aqua-blue (might be hemi) and is just as bubbly as the one in the middle. All of them have hardly any damage and are NEAR MINT.

Made this new insulator collector VERY HAPPY!!
