Going through my late Dad's belongings, we found an interesting old 8-page newspaper: The Call, Nov 2, 1940, a Socialist Party weekly.
All I can find out so far says is that The Call ceased publication in the 1920s, so this 1940 edition is peculiar. It calls itself Volume VI, issue 43, total no. 266 so it sounds like it had been running for a few years at that time, and not just for the 1940 election campaign.
Here's a scan of the first page (2 images)
The political ranting is pretty interesting.
Based on a quick search in my university's library catalog, it seems to me that you're looking at the version of The Call that was published by the Socialist Party of the USA in Kenosha, Wisconsin. I see several other similar papers with similar names, which I imagine is the source of the confusion. Here's the entry I found:
