Ihe Golden Bright-Frome Finder
The TOWER
CAMERA
embodies o new principle of ronge-
finder/viewfinder optics. Eosy sighting is now possible
with the TOWER oversized finder, eliminoting squinting
ond stroin on the photogropher's eye. A new Golden Frome
within the viewer itself shows you exoctly whot will be
within the picture. Regordless
of whot ongle your eye is
ot, the Golden Frome is occurqte.
In oddition to these odvontoges, the TOWER FINDER
AUTOMATICALLYcorrects for PARALLAX. Regordless of
the distonce being f
ocussed otr, ond regordless of the
position
of your eye in relotion to the f

Frome
shows you exoctly whot the film will receive.
