DIN 1451

Din Modernization

I did intend to post here before it was finished asking for comments and alike, but now it's done already.

For learning fontlab studio I took my favourite font DIN 1451 and added some ligatures. When the course entitled "Project work" came around I had already set my mind to either doing my own complete font, or modernizing DIN as far as time would allow me to. The course gave me 100 hours, but I likely put in closer to twice that.

Is this a commercial version of DIN 1451?

I followed a link from Wikipedia's article on DIN 1451 to this very broken-looking site containing downloads of public domain traffic signage fonts. They all appear to be so, except one download that I'm not sure about, this German one, which contains DIN 1451. Here's a sample image, metrically kerned. So, is this a commercial version of DIN 1451? Thanks!

(I didn't know if I should plop this here, in Release, or in General. Sorry if this isn't the right one.)
