I created illustrations for posters on eco-friendly transportation for the Moscow Transport Museum. Each poster corresponded to a letter of the alphabet and an ecological term related to eco-friendly transportation. I illustrated the letters "И" for Injector engine and "Ъ" for Production volume. The posters with the letters were displayed at various subway stations along the green line. Later, an eco-ABC book featuring all the letters and eco-friendly transportation terms illustrated in the project was released.
