"Anchor store" from the 50s?

[Paul McFedries]

The December 8, 1975 issue of Business Week says that "In the 1950s, the big
'anchor stores' that acted as magnets for customers of suburban shopping
centers -- and often owned them -- demanded and won considerable say over
the rest of the tenant mix." This has got me thinking that the phrase
"anchor store" was around in the 50s. Can anyone confirm this or give an
earliest date for this phrase?

Thanks.
