This is a Campbell's Soup magazine advertisement from December of 1929. Although the crash of 1929 was in October the full blown depression era was just beginning and would last through most of the 1930's. Interestingly the cost for a can of Campbell's Soup in 1929 was a whopping .12 Although that might not sound like much compared to today's cost of about 1.25 per can it is important to note that if you'd put that .12 in average DOW listed blue chip stocks at the time it would have become by now approximately $4.40
DOW 200 vs current DOW 8400 = 42x increase. So be thankful that Campbell's soup remains ... a bargain even in these troubled times.
