A rather specific and bizarre request:
Tell me about trends in Christmas Cards in England from the 70’s. Popular designs, companies, colo(u)rs, etc. Were they generally the folded kind that came in envelopes, or was it more common to send postcards? Glossy finishes or matte? Were embossed designs popular?
The 70’s happened before I was born, and the UK is all the way across that Atlantic Ocean, so I’m afraid my knowledge on the subject is rather sparse.
