Logos 500 Tactic Puzzle

Tactic's logo mess. I borrowed this at the Helsinki Puzzle Club's first event in Oodi, where we assembled other people's puzzles. Quite a fun puzzle, but not the easiest, even though I like the details.

 Surprisingly many similar logos were found in several locations in the puzzle, so you really had to look closely at the picture. Small logos also can fool you if you try to collect pieces by color.
