Unconfirmed rumours suggest the Thames Ironworks original Union Jack badge with TIW FC written on it might adorn the third shirt.
If true, this means the shirt can not be used in competitive matches but could be used in friendlies with the speculation that West Ham could wear it when the Hammers meet Juventus on Sunday 7th August in the former Olympic Stadium.
West Ham produced a teaser during the Home Kit launch video outside the new club store with a picture of Mark Noble, Michail Antonio and Aaron Cresswell dressed up in workmen overalls with Cresswell an Iron ship building hammer with the date 01-08-16 and sponsor Betway above it.
