First three were as follows:
As you can see, quite nice pieces but most retailers are sold out of all three. Some still have the ROTJ poster, but ANH/ESB are gone, gone, gone from what I've been able to search out. Revenge of the Jedi is pictured above.

There's a second ANH version as well, Style D
Plus the Revenge of the Sith above and the Episode III style A above.
