Tang Pitcher

Flip top Tang pitcher. I think this was from the late 60's or early 70's. No problems, but the cardboard circle on the top of the lid is still in place. I can remember it wouldn't come off and it was stored in my cabinet this way. It was not one of my favorites and never used, so the label just stayed. The graphics were scrubbed off originally when it was washed. I am now afraid to remove for fear there will be a difference in the color. Plastic tends to fade slightly with age and sometimes an old label removal will leave a brighter spot. It is marked with an anchor for Anchor Hocking. I need your zip code to calculate the postage.
