Here's an old photo of the Henry Mack Confectionery at 1434 Pearl Street, taken around 1904. Henry Mack sold confections, cigars & tobacco. Henry is one of the men standing in the front door. This building was in the middle of the 1400 block, close to where Liberty Puzzles, The Christian Science Reading Room & Kilwin's are today. Liberty Puzzles - known throughout the country for their amazing wood puzzles, are made right here in Boulder. Take a stroll down Pearl and go say hi to them!
