While the daybill is very nice, you're comparing it with a one sheet.
And even though Peters is in B&W on the one sheet, I still prefer it to the daybill.
Why? Because the daybill artist altered Jean Peters' outrageous anatomy, cropped it all to hell and then covered it with type.
(Not to mention all the dead space at the top of the daybill.)
If the insert didn't have the cheesy photo at the bottom, it would easily smack down the daybill.
As it is, I think it's a toss-up between the similar formats.
