Avoca Stock and Sale Pavilion at the Pottawattamie County Fair Grounds in Avoca. The Fair Board was organized in 1897. At the time of Avoca's Centennial this building was still being used for weekly stock auctions. (From "Avoca Historical Book 1869-1969" p. 39) From an article in the January 31, 1907 "The Journal-Herald" newspaper, the initial sale in this pavilion was held Saturday, January 26, 1907. It said that the cost to build of $3,500 was nearly all contributed by the progressive stockmen of the vicinity. The barn part of the building is 114 feet in length by 56 feet in width. The sale ring part was built in an octagon shape and could seat 700 people.
