A link making the rounds to the site  Tenth Letter of the Alphabet focuses on something which may be of interest to you called "Anatomy of a Logo: Star Wars."  It looks at the evolution and many revisions of the famous logo, with lots of examples from licensed products you own or have owned with things like a changing, more pointy "W" and Marvel Comics' revisions to the classic eight letters we now all probably have, in some incarnation, by the thousand in our storage units.

The Hollywood Reporter posted an article called Power Lawyers: How 'Star Wars' Nerds Sold Lucasfilm to Disney which details all sorts of fun little tidbits, like how they went and confirmed Lucasfilm really did own all the copyrights and trademarks and what have you for hundreds of characters which are now in the hands of the House of Mouse.
