A fleet of elegant six-metre class racing yachts heels in perfect formation across the grey-green chop of the Oslofjord — their tall white Marconi mainsails numbered N55, N64, N40, N65, N61, and N62 catch a freshening breeze as a distant headland and faint shoreline structures mark the familiar contours of Norway's most storied sailing waters, the whole scene captured in crisp real-photo postcard silver by a photographer whose small crowned emblem device appears in the lower right corner of the image. The Oslo Fjord has hosted international sailing competition since the 1890s, and the six-metre class — an ISAF International Rule class — was an Olympic discipline from 1908 through 1952, making this card particularly resonant with maritime sports history; the Oslo 1952 Summer Olympics included sailing events on the Oslofjord at Bygdøy.
