We know that Fred M Ackerson was the District Attorney for Niagara Niagara County from 1908 - 1917 and was also a Scottish Mason. What we don't know is who glued his advertisements on the barn wall and why.
Another thing that we know is that both Chas. F. and E. E. Warren used the same barn for their businesses and proudly tested their ink stamps on the same wall and luckily those have endured the years better than their choices in art and advertisement.
Chas is presumably Charles F. Warren who lived from 1856 - 1930 and E. is probably Elmer Warren 1881 - 1947.
If anyone has any information and can shed some on this little mystery we would love to hear what you have found.
