Al,

This might be pretty obvious (and not need mentioning ... but just in 
case... I'll go ahead and say it), but the oval enclosing the CITRO 
embossing on the bottles is doubtlessly meant to represent the outline 
of a lemon, the CITRO logo (which you see clearly depicted on the 
counter dispenser), and LIKELY also to be the reason the "G" encircling 
the "M" in the mark is difficult to discern as a capital "G" ... 
precisely because it was "stretched-out" into an oval-shape, also meant 
to represent the outline of a lemon.

Best regards,

Bob
