Christopher robin bump down stairs

I was wondering if you could assist me in finding out more information about a figurine I have had for 23 years.

This is a figurine of Christopher Robin and I believe Edward bear. I have searched tirelessly on the Internet but been unable to find any information about the figurine itself but I have been able to find information about sketches and prints made.

I believe it is made from porcelain, it measures at 2.5inches in length by 3 inches in hight and around 1 inch wide. It contains a Disney stamp on the back.

There is no sign of damage or repair.
