\1 TeackHsTPdt // No wonder teachers are singing the praises of the Tecnifax Transpaque projector. It not only provides them with a versatile tool for improved instruction, but also offers a combination of odvantages not available with any other overhead projector: NO "STAGE-GLARE" ... the Transpaque's unique optical system concentrates light on the screen, not in the teacher's eyes. HIGH LIGHT-OUTPUT . . . projected images are bright and sharp ... no need to pull down shades, or dim the lights. LOW SILHOUETTE ... no high projection head to interfere with pupils' view of the screen. STABILITY . . . thp Transpaque's broad base and low center of gravity insure trouble-free performance under all conditions. Furthermore, Tecnifax provides, without charge or obligation, training in the utilization of the overhead projector. This enhances its effectiveness in the classroom. For additional information on the Transpaque projector and the Tecnifax training programs, please write to Tecnifax Corporation, Holyoke, Massachusetts.
