SESAME STREET OLD SCHOOL CLASSICS: Episode 598-- Part 7 of Snow on the street! 

"Snow on Sesame Street" is a Sesame Street story arc that took place over several episodes in Season 5 (1974).
During the first two weeks in September of 1973, the Sesame Street set was dressed with snow to accommodate the taping of a dozen episodes set during the winter time. The scheduling block was organized this way primarily to best utilize work done by the production staff in manufacturing fake snow and incorporating other winter elements into the set and props.
