When My Friends Ask Me What ISaw inEurope I Get Out My Radioptican and Show Them The radioptican shows my photo snap shots ten or twelve times actual size; it reproduces post-cards in all their color and detail. I have seen it used in all sorts of lectures and classes. It shows everybody just what the speaker is talking about. This radioptican takes any printed thing that measures no more than 5 x7 in. and projects on the screen an image that is guaranteed to be the best procurable from such a The projector. Radioptican works by electric light; is con nected up like an electric fan. There is also an acetylene model - the latter complete with generator, ready to operate. If you think you would like to own a Radioptican I suggest hat you write for a card which entitles you to a free demonstration and gives you the name of the nearest dealer. Be sure and ask for the book,"Home Entertainments," and read the guarantee tag that is attached to every machine.
