Readers of a certain age will remember the delight that was Vision On. Presented by avuncular art legend Tony Hart who died last year, it ran from 1964-1976 on the BBC and showcased art and animation from artists and kids alike.
Two of the most memorable things about it are The Gallery theme and the great Vision On logo, designed by Tony Hart himself. Happily Trunk Records are selling Vision On prints and t-shirts. Tony Hart's estate get some of the proceeds and they're selling out fast, so get in there. (Thanks Andrew for the tip).
