gone into bankruptcy. But we're all right now, and we're mighty grateful to the 

 M. C. O. You belong to the M. C. O., or at least to "the M. C. O. crowd," and we 

 want you to share in this testimonial of good fellowship. 



And, then, of course, it is an advantage to us. We don't deny that. A good 

 big bunch of "easy" subscriptions (easily obtained, that is) is a welcome asset, even 

 if there isn't any margin of profit in it. You can't have too much of this "neutral 

 stuff," which at the least pays its own expenses, when you are facing press-day. 



We are not pretending to sell "below cost." We couldn't do that if we wanted 

 to. But here is the secret of it. We are selling you the books minus the selling 

 cost. That's why we can make you this 



EXTRAORDINARY OFFER 



(Good only till August 1st, 1920) through the courtesy of the M. C. O. management. 

 Better sign up one of these blanks and fire it back at us right away — before you 

 forget about it — because the "collecting season" is a very distracting time. 

 Cordially yours,
