Willy Black

"Honest" Willy Wagstaff Black was a street vendor who worked in Diagon Alley in 1915. The Ministry of Magic issued a warning about him in the Daily Prophet, alleging that he sold defective merchandise, including loose-bottomed cauldrons and wands that had to be recalled after several people were burned by them. The street cart company was called Honest Willy's Magical Merchandise. Not long later, a distant relative of his, Cygnus Potter, re-opened the street cart company, but this time, began to sell reliable merchandise.
