This advertisement from Spector's Juvenile Department Store appeared in the October 6, 1954 issue of the Sandusky Register Star News. Spector's was located at 138 East Market Street during the "baby boom" years of the 1950's and 1960's.(Spector's continued to do business in Sandusky until 1981.)
The children featured in the ad are wearing "Nitey Nite" pajamas, made of cotton that was Perryized to resist shrinkage. Toddler sizes came in either a Cinderella or tugboat print. Girls pajamas had a spinning wheel print and ruffle trim, and an extra long shirt for growing. Boys' pajamas came blue, green and yellow prints from sizes 2 through 8.
Many parents and grandparents in the Sandusky area shopped at Spector's for their young family members. (Sadly, many of those shoppers are now buried in cemeteries of the Sandusky area.) Another advertisment for the "Nitey Nite" line of children's sleepwear appeared in the September 12, 1955 issue of Life Magazine, accessible at Google Books.
