Now, 52 years later to the day, a minor mystery about that cover has been solved.
Sometimes thought to be a painting, the image, it turns out, was a Victorian-era photograph of a man who made thatched roofs for cottages in Wiltshire, a rural county in southwestern England. His name was Lot Long and he was 69 at the time, according to Brian Edwards, a researcher who found the photo.
Mr. Edwards, a visiting research fellow at the University of the West of England, stumbled upon the picture in March while scouring the internet for new releases at auction houses that might be interesting for his research, which includes the area’s well-known landmark Stonehenge.
As he was looking through a Victorian photo album full of landscapes and houses, Mr. Edwards noticed a photo he had seemingly seen before.
“There was something familiar about it straight away,” he said in a phone interview. (Mr. Edwards was the proud owner of a “Led Zeppelin IV” LP from the year the album was released, he said, and he listens to it to this day, albeit on a CD.)
