Here are two reproduction IPB Creature From the Black Lagoon playfields.  The playfield on the left side was done by IPB and they ran 20 of these custom NUDE playfields.  The playfield on the right side was made by IPB but someone changed the artwork to make the girl nude.  They did a good job but sold it as an ‘original IPB nude version’ playfield.  So beware if someone on eBay list a FAKE nude IPB playfield and they are asking a lot of $$$ for it.   IPB only made 20 of their custom NUDE Creature playfields.
