What the advertisement says:
The beret and the beard help. But blue jeans are as vital as North light to his creative spirit. Jeans are standard equipment with a lot of unusual people. Wranglers are the jeans they choose. We can’t promise you a one-man show at the Metropolitan; but we can give you the same lean, slim fit, the same sure-sizing that every artist wants. Pre-shrunk to the right size before they’re even sewn together. In sizes for all the artists in your family. From $2.49 to $4.29.If you look closely at that beard, you’ll see that it’s pasted on.
[Found while looking for something else in Google Books’ Life archive. There was a series of “________ wear Wranglers” advertisements in Life. This one is, I think, the goofiest.]
