“Igor Sikorsky (May 25, 1889 – October 26, 1972), born Igor Ivanovich Sikorsky was a Russian American pioneer of aviation in both helicopters and fixed-wing aircraft. He designed and flew the world's first multi-engine fixed-wing aircraft, the Russky Vityaz in 1913, and the first airliner, Ilya Muromets, in 1914. After immigrating to the United States in 1919, Sikorsky founded the Sikorsky Aircraft Corporation in 1923, and developed the first of Pan American Airways' ocean-conquering flying boats in the 1930s. In 1939 Sikorsky designed and flew the Vought-Sikorsky VS-300, the first viable American helicopter, which pioneered the rotor configuration used by most helicopters today. Sikorsky would modify the design into the Sikorsky R-4, which became the world's first mass-produced helicopter in 1942”. – Wikipedia

Could you ever have guessed that so many superheroes would meet together in one photoshoot? This scenario becomes possible thanks to the project of Sasha Goldberger. He was able to accomplish this by transporting modern superheroes into Elizabethan era. Some of the superheroes, such as the Cat Woman and Wonder Woman, look very natural in their new old-fashioned outfits. On the other hand, Ironman and Hulk look very peculiar in their newly acquired outfits. However, such innovative approach is very popular nowadays. People are fed up with dull and uninteresting ideas, which make them grab onto anything peculiar such as this project. (Photo by Sacha Goldberger)

“Very small forest-dwelling wallabies are known as pademelons (genus Thylogale) and dorcopsises (genera Dorcopsis and Dorcopsulus). The name wallaby comes from the Eora Aboriginal tribe who were the original inhabitants of the Sydney area. Wallabies are herbivores whose diet consists of a wide range of grasses, vegetables, leaves, and other types of foliage”. – Wikipedia
