Here’s a logo I prepared for a new US brand of sunglasses. A tithe means a one-tenth part of something, in the past paid as a contribution to a religious organization or compulsory tax to government. Nowadays, it usually a voluntary contribution. In case of this brand, the name represent the concept of giving away 1/10 of profits for charity causes. The small simple icon on top of letter „i” is used to suggest that 1/10 part.
