Yes, the World Tail BPs were very nice indeed!
There are several variations of the BA BPs. There is the standard light blue issued at Check-In Desks, the darker blue with the "e-service" in the background (at SSCI) and I have noticed that at ABZ they issue slightly different BPs IIRC they don't have the three boxes for Gate, Seat Number and Boarding time on the left stub and instead have just one long box and the one underneath for FF numbers. Yes, I have been bored recently!
