This issue has variants.
Story continues between Sub-Mariner (Marvel, 1968 series) #39 and #40. Pages 12 and 13 are half art/half ad. The colors on page 6 are completely wrong as Peter Parker has black hair and Mary Jane has blonde. Colors credit from Bullpen Bulletins page in Daredevil #76, which says Palmer colors the Daredevil stories he inks.
