LECTURER FOR 1.A.S. 70th ANNUAL MEETING 
Joseph Antos of Big Rock, Illinois, will be the featured speaker at the 
banquet of the Illinois Audubon Society on Saturday, May 13, 1967, at the 
Leaning Tower Y.M.C.A. in Niles, Illinois. A noted nature photographer 
and outdoorsman, Mr. Antos has developed the Color-Blend sound pro- 
jection system, in which twin projectors, working alternately, project and 
blend color slides for dramatic effects. 
At the Annual Meeting, his subject will be “The Rockies,” a new 
serics of color slides compiled during camping expeditions into out-of-the- 
Way mountain valleys. His pictures have been featured at national meet- 
ings of the Photographic Society of America and at many other meetings 
of outdoor groups. 
Other naturalist-photographers at the 70th anniversary meeting of the 
Society will be James Weaver of Rockford, who will show color slides on 
hawks and owls; and Charles Westcott, Director of the Crabtree Farm 
Nature Center near Barrington, who will present an illustrated talk on 
the new wildlife preserve. The Annual Meeting will be held on May 12-14 
at the Leaning Tower YMCA, 6300 West Touhy Avenue in Niles (just north 
of the Chicago city limits); full details and reservation forms will be mailed 
to all Illinois Audubon Society members in March.
