As the grooming in image #3 underscores, most or all of these pictures are twenty or more years old. If Gillette has its way, humans will be shaving all hair in a time to come.
Nonetheless, image 3 is in three-way tie with images 5 and 6 for my favorite of this collection. Thanks for posting them.
Images 4 and 6 are from the old "Tickling" and "Ticklish!" magazines that came and went too quickly in the early to mid 1990s. The ticklee in image 6 is one of the best I've ever seen, at least for still photo tickling.
Empyrium, that rooftop shot (image 5) you admire hits every mark. The girls are fetching, the ticklee's at least partially nude, and the tickler-ticklee interaction's compelling. If there's more to this than just that one photo, I'd love to see it.
