Christopher Columbus wrote in his logbook that on October 12th 1492 he picked the Royal flag, and his captains two flags which the Admiral carried in all the ships as Ensign, each white with a green cross addorned by old Gothic letters "F" and "Y", both green and crowned with golden, open royal crowns, for Fernando and Ysabel. With these three flags he took possession of Guanahani island (nowadays San Salvador).  These were the first European flags to fly over America - provided the Vikings did not display one earlier; Christopher Columbus flags are dyed on 100% nylon and finished with canvas header and brass grommets.
