I forgot all about this fad until being reminded of it when I saw this feature in an old 1973 Popswop magazine I have.
Embroidered pockets on jeans.
I have a vague memory of it being a trend the older teens indulged in as I can't recall anyone from my age group (14/15) going about in these back then.
Anyway, some of the embroidered images shown are - a Monte Carlo scene, Camel Cigarettes, flowers and a Miami scene.
