The R.R.R. Tricycle

This was a highly requested film, back in the days when film meant a 16mm film reel. 
In fact I was surprised to read that the film was created in 1981, it seemed to have a 70s look & feel to it (the book was published in 1978).

This is 'The remarkable riderless runaway tricycle' by Bruce McMillan. 

It began as a picture story in which a tricycle, whose young owner distractedly abandons it, ends up in a dump, but escapes and careens around town evading adult humans in a series of humorous hi-jinks and then returns, at last, to its downcast young owner.

Then Evergreen Productions made it into this 10 minute film. Enjoy.
