Antique Dutch postcard from circa 1910-1915 showing 'Een Zomerdag Aan De Zuiderzee' (a summer day on the Zuiderzee in the Netherlands).
From the back: '370 Uitg. Firma F.B. den Boer, Middelburg'
The card is unused and in very good condition with some minor yellowing from age and a light one inch surface crease on the top right corner (see photos).
