Heller and Plastic Philosophy?

I found some great vintage plastic Heller plates on Saturday at Goodwill.

They had them in stacks of three with rubber bands around them.

I really like this stuff.

I think I have enough of this for now that I can sell what I found this week.

I was washing these plates, so I could take pretty pictures of them and I found a post-it note -in between  a couple of plates.

I don’t know if the post-it note was there and the Goodwill workers just did not see it – or did a worker in the back room put that note there?

ONE LOVE

What on earth does this mean?

Is it a Universal Truth, or a simple longing?

One is the loneliest number.

Love is all you need.

Goodwill Philosophy or???
