Kraven’s Last Hunt is an all-time Marvel classic, and one of the best Spider-Man stories ever told.
The six issue collection also predates the modern crossover/tie-in phenomena by a good 30 years (published in the fall of 1987), hence the need for some reading order guidance.
You can generally solve this problem with $10 or less by buying the collected trade.
For everyone else, here’s the order you should read the issues spread across Web of Spider-Man, Amazing Spider-Man, and Peter Parker: The Spectacular Spider-Man.
Web of Spider-Man #31
Amazing Spider-Man #293
Spectacular Spider-Man #131
Web of Spider-Man #32
Amazing Spider-Man #294
Spectacular Spider-Man #132
