Just for fun, let's put the date on the ad as 1925.
Based on average prices of average items bought by average Americans, $1 in 1925 would buy the same as $11.74 now. . . . (See What is a dollar worth?)
So, to get a dozen of those Favorite boxes, instead of the 74ยข it would take in 1925, you'd need to fork over $8.69 this year.
That's wholesale, right?
