1949 Budweiser Beer Ad - Drink Bud for Five Days Then Try Another Brand

This original 8.5 x 11" magazine ad from 1949 encourages you to take the Budweiser Taste test, by drinking nothing but Budweiser for 5 days in a row and on the Sixth day try a different brand to convince yourself that Budweiser is the best.  The ad is untrimmed from it larger 11 x 16" master page but the image has been cropped to focus just on the ad portion.
