In the classic movie, "Miracle on 34th Street..."?

There is a scene in the advertising department of Macy's where a group of women are pasting ads from other stores into books for reference by sales clerks. A man stops another man and says something like, "We need more books, Joe." Joe says he'll get some right away (or something like that), and a blonde woman calls out, "And I need more wanamakers!"

Does anybody know what she's talking about? Wanamaker's was a big department store in Philly and NYC when the movie was made -- Macy's even bought out Wanamaker's in the end -- but the context of what she is saying doesn't make sense...unless she means she needs more ads from Wanamaker's? Even then, that's kind of a weak interpretation of the line, I think.

I know Wanamaker's invented the price tag and the white sale and cash returns...could she be referring to any of these?

If you've got an answer, I'd love to hear it! Thanks.
