June 1938. In Memphis, hundreds of colored laborers congregate near the bridge every morning at daylight in hopes of work chopping cotton on a plantation, where they are taken by truck. Reduced acreage has made employment scarce for this class of seasonal labor in all towns. "You can't live the commonest way on six bits a day. Not alone nor no way. A man like me can't get no foothold. It's a mighty tough old go. The people here in the morning are hungry, raggedy, but they don't make no hungry march." View full size.

Along the lines of the Beaver Letter, we're excited to present the Jim Letter from the opening credits of "The Office." You might think it would have something to do with the Dunder Mifflin paper company's Scranton branch, but actually it's a Los Angeles Department of City Planning (zoning) document showing revisions to the L.A. Municipal Code. Specifically, Section 12.22.C.20(f).
