Hibner, a Polish graphic designer born in Warsaw in 1931 was an important figure in the Polish school of poster design. Here are just a few of his wonderful book jackets and film posters from the fifties and sixties.
Here are a few by this wonderful and prolific polish illustrator. The simple color palettes seem so fresh to me. Each of these uses 4 or less inks. And the forms and line work make me quite envious... Stanny's design and illustration grace hundreds of books. Thanks again to Iskry on pinterest. There are enough great polish book jackets there to make your eyes jump out of your head. Also check out hippopotami studio for more polish book design.
