These sturdy old-fashion Oiled Paper Umbrellas could be counted on to offer all-weather protection with 100% confidence. The earlier ones were plain, with no decorations or colorful patterns. Only the ribs were painted, with a dark green color on the outside.
[A far cry from flimsy modern double-collapsing or triple-collapsing contraptions, which are waterproof only if the rain is not serious, and threaten to be gone with the wind in face of strong gusts.]
But these were bulky and heavy and a hassle to lug around everywhere. The last time I used one was probably in the middle of the last century, when I carried one to school on wet days. Two or even three children could easily be accommodated under one of these brollies.
