From the album: Mercian’s pens
This is just to show the logo on the top of the cap of my early-1980s Pelikan M400 in Brown Tortoiseshell.
The incised lines of the logo have been filled with brown paint, to match the pen’s body.
The contemporary M400 fountain pens in Pelikan’s traditional Grün-schwarz stripes had their cap logos filled with green paint.
