How to go about creating 54 individual post cards that create a map when all put together?

I need to create 54 individual post cards/ brochure cards that all have different graphic designs on them. When they are all laid out they need to create a map of the world. For instance, one of the 54 cards will have just a small section of the world (maybe a country) and then when placed with the others it creates an image.

I have photoshop and illustrator but have never used them before. Willing to learn. Just need to know if this is doable.
