I think the entry fee (or submission fee or application fee or whatever the appropriate synonym is) to have the organization being promoted by Aperture consider you for the grant was actually pretty modest, as is fitting for value of the grants, one of which was for $1000 and the other for, as I recall, $3000. It was the appearance of "Pay Now and Submit Later" at the top of the entry form (or submission form or application form or whatever the appropriate synonym is) which caught my attention, and upon which I was primarily commenting.
Lest anyone think otherwise, I admire much of Minor White's work, both photographic and editorial. Minor White edited Aperture from 1952 to 1975, and died in 1976. Much has changed in the world of photography and consequently at Aperture since.
