In most cases, yes. Brick from roughly fifty years ago is typically a standard machine-made modular size, so the harder part isn't the shape, it's finding or blending a color and texture that reads as one wall instead of a patch. When the original color run is no longer manufactured, a mason matches it by sourcing a close equivalent or blending two or three similar bricks across the repair so no single seam stands out.
Brick color comes from the clay source and how it was fired, and both of those can change even within the same manufacturer over the decades, which is why a brick made in the 1970s isn't guaranteed to still be in production today. Fifty-year-old brick usually isn't the hand-struck, irregular brick you'd find on a much older farmhouse, it's typically a consistent extruded unit, which actually makes color the main variable to solve for rather than shape or size.
When an exact match isn't available, the more reliable approach is blending several close options across the repaired section rather than betting on one brick reading as identical. Salvaged brick pulled from a matching-era building is sometimes the closest option available, and weathering on the existing wall also gets factored in, since brand-new brick straight from the yard often looks slightly brighter than fifty years of sun and grime until it weathers in on its own.
There are limits to how close a match can get, and Chelo's Brick & Stone will tell you upfront if a section is going to be noticeably different rather than promising a seamless result that isn't realistic. In some cases the better long-term answer is choosing a brick that complements rather than exactly replicates the original, especially if the fifty-year-old brick was a discontinued specialty color that simply isn't reproducible today, so setting expectations early avoids disappointment once the patch is finished. Homes around Galax and Independence with brick from that same mid-century era often share the same handful of common color runs, which sometimes makes sourcing a genuinely close match easier than it would be for a truly one-of-a-kind older brick.
