Been meaning to post this one for a while.
I imagine it's mere chance - both ads have been appearing for sometime in the New Yorker but always on different pages and never, as here, one above the other. Of course, these ads are one of the many reasons for still having a subscription to the paper and ink version. Someone who does maths should be able to work out the next time these two are likely to come into conjunction.
'Course, it might not be chance. Maybe a temp in the small ads department or setting the page has a wicked sense of humour.
And the New Yorker has visitied similar territory before - the June 9/16 front cover.
