Wow, you don't see these on eBay very often. Nowadays, the company known as Creative Playthings makes nothing but slides and playground sets. But back when Creative Playthings was Creative Playthings, this was about it.
The Indoor Gym House was introduced in 1962 and was sold through at least 1980. It was a simple, little flatpack wood & masonite set you assembled at home. There's a little cube to climb into, and a little slide that you reach from a little two-step ladder.
On the models built before 1980, there's also a little gap at the top of the ladder where, if you're a toddler, you can wedge your head in and strangle yourself to death. Or get permanent brain damage. And if you're a 2-year-old in California in 1982, two years after Creative Playthings and the CPSC first issued a recall and began a ladder replacement program, you can still find a Gym House with an original ladder, wedge your head in there and die.
Except for the photo above, which shows the deadly gap, the CPSC notice doesn't say how to identify a safe replacement ladder. A 1980 Washington Post article says that the original gap between the top rung and the bottom of the platform was 5-6 inches, and that the replacement ladder expanded the gap to 7.5 inches to prevent entrapment.
So even from the visible lower rung and bolt in the eBay photo above, I can't tell. In the absence of photos and a tape measure, it'd be safer to assume it is in "original deadly condition."
