Raised white letter tires in back and blackwall tires in front, would it look ok

In the early 70s, most of the wider performance tires that you could buy at the local speed shop, like M/t and pro trac, came only with raised white letters. Most of the guys would go wider in back and keep the stock tires they had on the front of the car. I can't tell you how many sets of M50X15" tires I sold at the speed shop.
