Former President Barack Obama’s influence in his presidential museum runs deep, from the Chicago location to the textured stone adorning its dramatic tower, art installations and a striped reading chairs that resemble ones in his own home. The Obama Presidential Center opens to the general public on Juneteenth after a celebratory dedication in Chicago with dignitaries. But tens of thousands of people, including students and journalists, have already been offered a sneak peek as crews finish final art installations and landscaping. The roughly $850 million project covers the political and personal realms of the nation’s first Black president.
