Eric Silver and company at Amalgamated continue to push their vodka client Ultimat, which is housed under the Patron Spirits umbrella. After taking its “Social Life Audit” several months ago, Amalgamated has now provided us with this interesting outdoor effort aimed at white collar pros in NYC and Chicago who apparently work nonstop and could use a booze break. The parties behind the campaign employed actual window-washers (hence the name) and snazzed them up to a bit in order to relate, we suppose, to the corporate workforce and send them a message in the process. How’s that for selling a happy hour. At least it looks like mission accomplished. Credits after the jump.
