The Festival of Empire was held in London's Crystal Palace in May-October 1911 to celebrate the coronation of King George V. A photo survives of an infant incubator exhibit which is found on many stock photo sites (and often mislabeled). The incubators look more like the original Tarnier/Auvard incubators than the Altmann or Lion-style incubators that were used in most of the other incubator baby exhibits around the same time. The only mention of this exhibit I have been able to find is a passing reference to it at the end of a short article about the "Model Day Nursery" published in the London Standard on June 10, 1911.
