This is the vintage you want... one of my better vintage finds ever. Mcdonald was a dry goods merchandiser and later workwear maker that specialized in selling clothing to railroad workers. Their factory was located in St Joseph, MO, I'm in KC, so a semi local product here. The factory closed down due to the depression in 1933. The most recent ad for this shirt with the Red Seal brand was 1924 on Google. Vintage chambray is awesome. Triple stitched seams, mint condition, crazy.
