This very cool sign is dated by the bench car seat. Reminds me of Francine, my beloved 1977 Chevelle. Not only is the sign still functioning, but the business too, just north of the Ballard Bridge in Seattle. Other signs on the building brag that Mac’s has been in business since 1948 (below). Photographic evidence from the Seattle Municipal Archives (also below) dates the business at least back to 1958. Note that the sign, which Mac’s has done a great job preserving, is present even then.
