Fascinating tract by the Bakers' Union about why people should eat only Union Made Bread (they somehow stamped the loaves with a union label). Aimed at prospective members, it includes a list of union benefits on the last page.
Contains a most unfortunate definition: "I" is for Indian / A good one (he's dead) /He'd been living yet / Had he used Union bread." Also "J is for Judge" has the judge ordering consumption of Union bread as a punishment (The writer didn't think this one through).
