It's a "Little collection of gengas" (original 
drawings) ... which makes sense since that is 
what's on the 22 small-scale pages that follow.  
(It covers only the "flower scene" in Episode 48, 
in which Eriol gives Sakura the flower to cheer 
her up, and Syaoran nearly erupts from jealousy.)

And "Sepia Kanden" is the publisher?  So this 
would have been sold commercially to fans?  And 
so there are other "little collections" that 
reproduce the gengas from other CCS scenes?

Anyone know how common these are?  I've never 
seen one before for sale (though to be sure I 
don't look through CCS non-cel merchandise with 
care).

Thanks, evilminion and others, for the support; 
though in truth I feel that the goal of higher 
education is to recognize just how many things 
there are in this world that you know practically 
nothing about.
