The pair were due to appear at the store before the game against Blackburn on February 2, but travel problems meant that Frank was unable to make it down from his Newcastle home.
Frank and Tony will now appear in the store between 1pm and 1.45pm, before making their way up to the Executive Lounges in the new stand, where they now work together as matchday hosts for the club's hospitality department.
They will be happy to sign autographs and pose for photographs, and there is also the chance for supporters to get their copies of Boys of '86 signed. The book recalls the record breaking 1985-86 season, when the prolific double-act set the old First Division alight and led the Hammers to within a whisker of the League Championship for the first time in the history of the club.
There is also another fabulous merchandise on offer throughout the month of February. Anyone purchasing a replica away shirt in a club store will receive a fantastic Fila wallet absolutely FREE.
