Star Wars Children's Book Mandela Effect

Many people argue over the whole Berenstein versus barenstain spelling,
as well as the differences between "Luke i am your father." and "No, I am your Father."
Many people remember celebrities names being spelled differently and the most famous name is what this "effect." is named after.

The Mandela effect.
Some people will remember Mr. Mandela becoming a leader.
Some people Remember him dying in prison.
some people remember his name as mandella.

is the following children's book i am about to share with you evidence for the mandela effect?

Before we get started , heres the information on the first page of the book.
STAR WARS
R2-D2 & C-3PO
DROID DUO

Illustrated by Ken Steacy
A Golden book NEW YORK
Golden Books Publishing Company, Inc., Racine, Wisconsion 53404

What we are taking into question here, is C-3PO's Silver leg from the original starwars movies.

in this children's book, C-3PO can be found with Golden Legs instead of as one silver.

Another movie Reference would be this.

But for some reason in this book he has two golden legs.

Is this childrens book evidence of the mandela effect, and is it possible that the history of the universe could have been changed like so they say?
