1957 Purina Checkerboard News Double-Sided Centerfold Magazine Ad #1265

This original double-sided centerfold magazine insert measures 10 x 13" when closed and 13 x 20" when open.  I cannot find a printed date on the item but I'm estimating 1957 - 1959 timeframe based on clues in the ad itself and knowing which magazines it probably came from.  Image 1 is the first page, Image 2 is of the inner two pages and Image 3 is the back page.  If you grew up in this time frame Like I did the ladies head scarfs are a great clue to the timing.  Very popular in 1957 and 1958.
