This diagram illustrates how to draw a euro symbol, based on official documentation, and has been prepared specifically for Wikipedia and released to the public domain.
The official diagrams of the euro symbol are copyrighted and downloadable from the official European Commission site, and include:
The official diagrams are provided in industry standard TIFF and WMF formats, and are meant to be imported into a graphics editing program, such as Adobe Illustrator or Photoshop.
The Wikipedia version was created with Adobe Illustrator and rendered in Portable Network Graphics (PNG) format. It bases the guidelines for construction of the symbol on the key data provided for the official symbol, but it was prepared from scratch and does not duplicate the official diagram, and it is released to the public domain.
A very similar color version of this diagram is available at File:EuroConstLargeColor.png, showing the official euro symbol colors. It's prettier to look at but correspondingly more difficult to read.
