New EPUB logo

The EPUB format in which Atlantis Word Processor creates eBooks, is steadily becoming the eBook industry de facto standard. The position of the EPUB format recently strengthened even further with the release of the bestselling tablet computer iPad which also supports this eBook format.

But even then, and as surprising as it might sound, the EPUB format had no official logo until now.

So, IDPF, the creators of the EPUB format, recently announced an EPUB logo contest. Anyone could enter the competition, and suggest a logo.

The contest is now closed, and the winner is Ralph Burkhardt from Germany. Here is his suggested logo, now adopted as the official logo of the EPUB format. We find it quite nice. What do you think?
