The Mexico Senior Center is inviting all former employees of A.P. Green and National Refractories to attend their celebration of their contributions to Mexico on Wednesday from 11:00 to 12:30.

Cake and ice cream will be served for all, and the Audrain County Historical Museum has arranged for all former employees to tour the refractory exhibits at no cost from 1:00 to 3:00.

A.P. Green first opened in 1910, and Mexico Refractory opened their doors in 1920.
