How long does it roughly take to assemble a Brick Mosaic I purchased on the Art4Bricks eShop?

 

This depends upon various factors. To mention the most relevant ones:

- Mosaic Size 
- Amount of Color Art Bricks
- Customer Lego Brick Building skills

 

According to our experiences, it takes 2 people roughly 2 hours to build a Brick Mosaic sizing 50x50 studs / 40x40 cm / 15.7x15.7 inch.
