This font is Gill sans. Gill Sans is a sans-serif typeface designed by Eric Gill and released by the British branch of Monotype from 1928 onwards. I think it's very special that the designer use the way that the heading of G connect with small ill sans.
Font: Futura by Paul Renner. This is a gorgeous and well-designed poster. The slight skew of the layout makes for a more unique design. I am a huge fan of the hot pink, grey and white. Futura is a beautiful and modern font!
