Based on out-of-copyright design by Rudolf Koch (died 1934).

Vector version of original PNG Image:Coptic-Cross.png, which was a quickie image to fill a gap in the Cross page. PNG was copied to Commons from en:Image:Coptic-Cross-so-called.png (uploaded on 17 October 2005).

Converted to SVG from the following vector PostScript source code:
