Many readers here will remember going downtown on a Saturday to buy shoes and other clothes. That day seems to have passed with retailers selling their stuff mainly in the suburbs. That’s mainly. In Hanover, you can still shop for shoes on a Saturday and other days to the week. Clarks Shoes, known as Clarks Bostonian Outlet, is open on the square, and there’s another dose of nostalgia now awaiting visitors. A local collector and Clarks employee Donald Hamme has put up a display of Hanover Shoes relics. Hamme told The Evening Sun in Hanover that when Harper “H.D.” Sheppard and Clinton “C.N.” Myers founded Hanover Shoes in 1899, the company’s motto at that time was to provide “the greatest shoe value on Earth.” Now Clarks customers get an extra value, a case exhibit showing memorabilia, courtesy of Donald Hamme. ‘I have enough to fill it three times,’ Hamme told the Evening Sun.
