1955 Quarterly on eBay
 

I'd assume that IHQ has archives of all editions of Quarterly (at least I hope so, can anyone confirm?). But, any other Alpha Gam collectors might be interested in this auction:

The Buy It Now price is $15. Guess if this is one IHQ is missing for some reason, that's not too bad of a price to recover a copy.
