Competition: guess the date of the Guardian article – week one

Pinpoint the date the story first appeared in the Guardian to be in with a chance of winning prizes including a ticket to a Masterclass of your choice

To mark the Guardian's bicentenary, we are running a competition for readers. We have selected six stories that have appeared over the past 200 years. There is a link between them, but just to make it a little spicier we will not be telling you what that link is.

Each of these six stories will be published on the Guardian website on successive Fridays, with the next four following on 14, 21 and 28 May, and on 4 June. On 11 June, we will publish the final piece along with the other five, alongside a form for entries. You must guess the date that each of the stories appeared. The first 10 randomly chosen readers who correctly identify the dates (or got closest to them) will receive prizes, including a ticket to a Guardian Masterclass of your choice, a ticket to a Guardian Live event of your choice, and merchandise packs of commemorative gifts to mark the 200th anniversary. All entries will need to be received by 2 July. The results and a list of winners will appear on 16 July. If more than 10 people get all six right, the winning names will be drawn from a hat (possibly metaphorical).
