Very interesting placard

Over the past few weeks I have been working on several sets of Bangor and Aroostook decal artwork. I came across something in this photo* that I had not noticed previously and I found it to be interesting enough to share. The placard on the door not only cautioned that the car contained newsprint, but the placard was actually shaped like a roll of newsprint. I plan to create this placard in HO scale and it will add a nice, prototypical touch to a BAR or Maine Central box car model in future. 

The lettering on the placard read, "NEWSPRINT" and the next line cautioned, "TAKE IT EASY". I can not discern the smaller writing below that. A mystery to be solved...

*BAR 5523 was a 1932 ARA design box car, built February, 1945 as BAR 65523 by Magor Car Corporation and renumbered to BAR 5523. As shown here at Readville, Massachusetts on June 28, 1958, it had been repainted in the "STATE OF MAINE" scheme with red, white, and blue stripes on the sides and black ends, roof, and underframe.
