The invisible host! 
Si 
’TEP IN. The room is empty, but every 
detail is an invitation from an invisible host. 
The air is fresh, yet you are com¬ 
fortable and warm. You look for 
the cause. Under the window 
seats are American Radiators, their 
slender columns in perfect har¬ 
mony with their surroundings. 
They are the visible representatives 
of the invisible host—the Ideal 
TYPE A Heat Machine, whose 
kingdom is the cellar, yet whose genial presence 
permeates every room of the house. In homes 
where he presides his popularity 
grows each year. For, by rigid 
economy, he pays back his original 
cost in the fuel he saves. 
To owners of homes, small or large, 
we offer a finely illustrated book about 
the Ideal TYPE A Heat Machine. 
It will be mailed without obligation on 
receipt of your request at either 
address below.
