A mix of unusual fonts and modern collage illustration works well on posters. The composition is easy recognizable and looks like even the colors were carefully selected.

Simplicity as its best. A simple photo manipulation is making these not really special photos into a nice form.

This is contemporary art. A truly remarkable design usually starts with custom type. Custom type becomes branding.

Overprinitng and hiding obsolete information in glossy black. Yes, why not. Black and bold is the final result.

A set of unusual elements in thy flyer works good, because different it is noticeable. But would live without the QR code.

Layouts like this always seems so simple, but when creating minimal layout all design elements are becoming so strong it is hard to find a working harmony.

Always a great plus when a simple  lenticular-effect can be adapted to all media. Especially when it creates the blurry effect on letters. It is not always important if you can read it, if it maintains a strong visual.
