LUDI, it's a ship name.
Our system helps everyday thousands of designers (famous or not) to find the fonts they need to complete their work. Using a database of 1,100,000 fonts the automatic font finder system identifies the font from images.
Yet sometimes the images are very complex, so other users need a bit of help.
If you recognize the font from the samples posted here don't be shy and help a fellow designer.
If you need help, first try the font finder. At the end of the process if the results are bad you will find a link that lets you post the image to the forum so other users can help you.
