I have a few antique Harpers.They are hard covered and about 2 inches thick.More of a book than what we know as a magazine.
Had many but sis stored them in a cellar with a dirt floor and ruined most.These 2 were salvagable.
One has an interesting article in it about smoking Opim for medicinal reasons.
Each edition is about 140 pages. I wish it was practical to print more of them. I wondered about the physical appearance. I figured they would be pretty thick but I didn’t guess a hard cover.
