Those where all made by scratch using whatever I had around from the OT with the original logos on them as a reference, I can't even tell you what fonts I used unless I go experiment again in Photoshop, I have them all on PSD format somewhere, I'll try to find them.
They're still a little rough around the edges, since I was trying to match up the "S" in ROTS to the "J" in Jedi, but never found a good way to do it, and the "N" in the ROTJ logo wasn't changed in the others, because I didn't like the way it looked in some cases, so I left it alone.
Originally I was going to use the logos on the upper left on the back side of my custom DVD covers, and the "Episode" style on the bottom front just to blend OT style with the prequels, but have put the whole thing on hold.
I've tried many,many variations on all of these logos, and always tried to keep the consistant style to them all so they all match up, I don't know if you noticed, but in evey logo except ANH I made
the most important part of the title the largest while "the and "of the" are the smallest, ANH is obviously a little different looking because it's only three words long.
I'd love to see what some other people have come up with for all six logos.
