Last week we set you a task relating to our forthcoming Top 20 logos issue: name the logo from its nickname. Here are the answers.

In the course of our research into our Top 20 logos we uncovered a lot of nicknames bestowed on logos by their designers and users, not all of them complimentary. So, can you guess the logo from the nickname?

1. The meatball
A. The original (and current) NASA logo

2. The ferret and dartboard
A. The old (pre-DRU) British Railways logo

3. The crows' feet
A. British Rail

4. The worm (two possible answers)
NASA (1974-92), CN (Canadian National railways)

5. The arrows of indecision
A. British Rail again

6. The bird splat
A. Mont Blanc
