Here's why it's unlikely to exist:
* Walt Disney died in 1966. While Walt Disney was heavily involved in the "True-Life Adventures" series, it's unlikely a compilation would be released using his name years after his death.
* "True-Life Adventures" was a running series, not a specific release date. The series ran from the 1940s through the 1960s with various films. A compilation like this would likely have been released earlier.
It's important to note that the "True-Life Adventures" series is very popular, so there are many compilations and re-releases available on DVD and Blu-ray.
If you're looking for a specific film or compilation, please provide more details.
