I have several printers blocks that look to have been used to advertise W.B. Wayt & son Wholesale Granite Dealers in Sac City, Iowa.  Wooster Wayt opened Wayt Monument Works in 1889.  In 1901, Leon Wayt (his son) became junior partner.  In 1906, the pair entered the wholesale business.  They did build a new building at the corner of 13th & Main in 1914.  The business was eventually sold in 1977.
