Designer: Andre EbelEpro are a manufacturer of childrens creative toys. The logo was developed in reflection of their tag / motto: "simple, creative joy" with the logo composed of simple shapes (based upon a circle) creatively forming a joyful face with an addition of an upside down "r". The type was built from scratch using a circular shape as a guide.
An image makes a thousand words. The magnifying glass, the pipe and its smoke send you thinking at Sherlock Holmes, the most inquisitive literature hero. They also fit pretty well as the letters in the text.
