Not really vintage, but possibly rare. In 1988 I was sent a 1989 Unipart Calendar photographed by the late Lord Lichfield, Her Majesty the Queen of England's cousin. I have discovered it has 13 months, the month of May appears twice. The calendar has Lichfield's signature printed on every page. As I have never seen a 13-month calendar, could this be worth keeping for its rarity value?
