Once again, an ad from yesterday — late 1971 in this case — caught my eye during my ongoing Silver/Bronze Age reread.
Iron-on patches had become popular in the 1960s as a way to individualize your clothing and show you weren’t just a tool of the establishment, even if you were wearing a generic denim jacket from JC Penny’s. Here’s some examples.

Ah, the symbols of the era: the Playboy bunny, the ankh, peace, Woodstock.

A somewhat quirkier mix on the bottom half of the ad. Though you’ll notice in both photos that ecology is popular as a symbol, just as it was a big theme for “relevant” comics.
With patches like these we were free to be, you and me.
