Engineer: If You Are a Patriot, If This Is Your Fight, Get Into It. Stop the Ammonia Leaks

Uncle Sam, holding a lantern, reaches over a seated engineer who is reading a newspaper headed 'War'. The caption ties patriotism and 'your fight' directly to a workplace task, stopping ammonia leaks in refrigeration plants, and a blank box invites a local bonus offer to be pasted in. The tell is the conditional 'If you are a patriot': the worker's national identity is made the reason for a maintenance duty.
