Focus on Angel in a Cage and analyze the Historical information.
A committee of local expert artists was formed to judge the student sculptures as well as an advisory group of Peck employees to help in deciding the winning design. Richard Pflieger was the winning student with a design called Angel in a Cage, which was a fiberglass angel suspended in a tower of steel fencing. The artist's inspiration came from the many fences throughout the Menomonee Valley in contrast with the numerous shrines with angels in the back yards of the Milwaukee south side homes. The committee suggested the artwork should be forty feet high for the best sculptural impact and biggest statement. Pflieger took almost two years to complete this sculpture which still towers today now in front of Emmber Foods Incorporated on Canal Street in Menomonee Valley.A structural engineer named Matthew Fuchs of the Milwaukee School of Engineering and fellow student Michael Pagelsdorf advised Pflieger to use 4 ½" steel pipe with ½" wall thickness when building the tower structure. Fence material and even labor were donated by Heritage Fence of Cedarburg. The angel inside the cage is fiberglass and resin which was made from a clay model and has a metal interior. 
This structure is a great example of cooperative effort of both public education and private business which has the power to create outdoor artwork installations.
