This striking stamp from the United Nations Office at Geneva, issued in 1974, commemorates the work of the Conseil Économique et Social (Economic and Social Council — ECOSOC). The design features three stylized blue human figures ascending a red staircase, symbolizing social and economic progress, cooperation, and collective advancement among nations. The background grid suggests data, planning, and development, reflecting ECOSOC’s central mission to promote economic growth and improve living standards worldwide. The UN emblem appears in the upper right corner, affirming the organization’s global scope.
