ZSL London Zoo Logo

Could anybody give me more information on the ZSL London Zoo logo design?
Especially the rounded letterforms with the animal shapes.
Such as who designed it and what typeface it is based on?


Work by Barraclough Associates, probably custom (manually rounded). Some suggestions for base font:
- P22 Underground Pro Heavy
- http://HTF Verlag Black
- Avenir Black or http://Next Bold
- Gill Sans Bold

Hi could it be 'Folks'?
