Picked this up recently.
Mantle 1960s Milk Meadow Sweet Cut Out resized.jpg
I'm assuming this is from a low-fat carton of Meadow Sweet milk. In Post 1853, I showed a regular carton of Meadow Sweet milk, and this Mick is the same as that, except for the color. Since the color of the Meadow Gold "cards" is based on the type of milk, green for low-fat and blue for regular, I'm assuming the same might be true for Meadow Sweet.
