I never bought the calendars, if anyone came to my house and saw one they would immediately spot that I belonged to a freaky religious cult.
The symbolism of the baptism picture is typical of JWs using "the world" to bolster their lowly status. With a backdrop of the refined classical architecture and the expensive dress and elegance of the female figure; they mislead the viewer into thinking their brand of christianity was about style and high fashion.
In reality these aspects of life are severely played down today by the deceiving JW organisation. Back in the first and second centuries the christ cults were mainly drawn for the 'great unwashed' peasantry who would have been far removed from the likelyhood of such pretentiousness.
