From the Cambrian Daily Leader, 14th April 1915.
Text: Instead of a pound of bacon or 1/6 worth of eggs buy a packet of Quaker Oats. You will save about 1/- and give your family much more nourishing meals.
[I suppose the idea was to make porridge for breakfast instead of cooking bacon and/or eggs, though the Cambrian Daily Leader was a Welsh newspaper, and I didn't think that anything resembling porridge was a Welsh traditional dish. But evidently Quaker Oats was already a national brand in 1915.]
