SPEAKING OF PICTURES
(continued)

A great twist in Pichel's turn as a professional smoke ring entertainer comes when slim Selma Peal, aged 18, steps forward, sits down on a pile of blocks and extends a leg in Pichel's direction. Then Pichel, standing about a yard away, takes a deep puff on his cigar and lets go a perfectly rounded smoke ring aimed at Miss Peal's toe. Floating slowly through air without losing it's shape, the ring settles gently around it's target.

As the girl extendsd her leg in Pichel's direction, he blows a well-aimed smoke ring towards her pointed toe.  The girl is a professional dancer known as Roberta.
The smoke ring slips around her toe without breaking its shape. For his demonstrations. Pichel smokes a free-drawing 10 cent cigar, preferably mild to protect his throat.
