Blackpool – new logo

Blackpool Tower, the sea and a football. A crest used by Blackpool in the ’80s, pictured right, also combined these three elements (if you choose to interpret its circular portion as a ball) for a look reminiscent of Nottingham Forest’s logo.

You can see Blackpool’s current crest on Wikipedia.
You can read about Blackpool’s crests over the years on Historical Kits.
