Found there are 2 different variations of the latest dark blue Celebrity X Cruises BlueChipClub Casino Players Card...

On the original BlueChipCard the reverse text starts "Your (BlueChipClub) membership..."

On the later BlueChipCard the reverse text starts "Use of this card..." but there are two distinct color variations of this card with the same exact text on the back. The earlier of these two cards was a metallic blue with the text "BlueChipCard' in metallic light blue and the Celebrity X Cruises logo in metallic silver.

On the second variation of this later card the front is a dark plain blue with the text "BlueChipCard" in plain light blue and the Celebrity X Cruises logo in plain white.
