These are full-page scans from the 1930 DeMoulin Bros. & Co. Fraternal Supply Catalog, which illustrates tons of pranks to use on new recruits. Most are fantastically elaborate and would never work in today’s society. I think my favorite is the Electric Spiked Pathway or maybe the Moral Athletics. Take a look and post your favorite one in the comments.
