3M celebrates its 40th anniversary at Green World!

3M held its 40th Anniversary Family Day at Green World on May 9, 1998.

On the vast green lawn of the square, a temporary carousel, snacks, and children's toys were set up.

There were also mischievous clowns playing with children and blowing up dog-shaped balloons.

It was filled with a warm, lively, and nostalgic atmosphere.
