Sorry for not being clearer, George - your were right in your post but unfortunately, as Tim said, "Advanced" is used
at the beginning of that article. Chevrolet/GM never used the term
Art Deco; however, the term fits nicely (and they are beautifully styled trucks).
And, as Tim & I posted, the Advance-Design trucks were introduced in 1947. Chevrolet/GM never called it 47-2nd; they just sold the 1946 style into 1947 until they ran out).
