Below is a better view of the writing on the back.
I've done a little research on the Milkette bottle now and found out a few things. On the bottom is the number 65 which I'm pretty sure is the date code. So, it is 1965.
I haven't found a lot on this bottle. I only found one similar bottle, which was on eBay and dated 1964.
The product is coconut milk. I never would have guessed.
I did find mention of Yoo-Hoo offering a coconut flavor, but haven't otherwise found any more on the drink.
Yoo-hoo began introducing new flavors to its lineup in 1995, including chocolate-coconut, chocolate-mint, chocolate-banana, and chocolate-strawberry. Yoo-hoo's other flavors have included vanilla, strawberry, cookies & cream, chocolate peanut butter, and chocolate caramel. The Double Fudge, banana, and Island Coconut flavors were discontinued.
