After suffering a fire almost three years prior and following subsequent litigation between the parties, the William D. Hardy Company of Muskegon, operating Hardy's Department Store, agreed in 1947 to merge its operations with a newly opened Herpolsheimer's branch location in Muskegon and proceed as Hardy-Herpolsheimer's.

[4] In a departure from the traditional department store format, Herpolsheimer's opened location selling only furniture, appliances, televisions and limited hardware in the Tower Building at River Avenue and 8th Street in downtown Holland in October 1948.

[10] Starting in 1985, the downtown Grand Rapids store was reduced in size, with the remainder being converted to a shopping mall called City Centre.

[11] With the City Centre "grand re-opening," Herpolsheimer's officially reverted to its full name, giving up on the shortened "Herp's" version from eleven years prior.

The full Herpolsheimer's name was restored to the downtown Grand Rapids, Wyoming, Muskegon, and Battle Creek stores.

[17] During the pre-Christmas shopping period, Herpolsheimer's operated the "Santa Express" miniature train on a monorail suspended from the ceiling of the basement in its downtown Grand Rapids store.

Herpolsheimer's produced a series of advertising cards in 1921 which featured pictures of notable baseball players of the time.

Long thought to be legendary, a trove of cards was discovered housed in a Band-Aid box in a 2019 estate sale.
