Three bygone color schemes. The first, which takes several variant forms, is fairly common, the second I've found only at the Wun-Tun House. The third — widely attributed to Peter Max but more credibly to John Alcorn — survives in many pop-culture collections but is seldom seen in public, and even the market where this psychedelia was sited may no longer be a going concern. See also this Bronx bombshell.
