The issue included 5 square stamps with denominations from ½ to 4 schillings. All used the same design - a combined coat of arms of the Free Cities of Lübeck and Hamburg (the two city states which were the sovereign lords over the Bi-Urban Condominium) - but the higher values were larger stamps. All values were printed in black on different coloured papers, except for the 3s stamp, which was printed in blue on pink paper. With Lübeck's sale of its share in the condominium to Hamburg in 1867 the territory was integrated into the adjacent city state of Hamburg as the "Rural Seigniory of Bergedorf" and the separate Bi-Urban Mail became part of Hamburg's postal service without any more separate stamps. Hamburg, including its Rural Seigniory of Bergedorf began using stamps of the North German Confederation in 1868.
