Using maps for  games is nothing new, we’ve blogged a number of times about card (here) and board (here) games but this is a first, a game you can only play if you destroy the map first.

Secret rivers…c2020 C17:40 (277)

Secret Rivers family game is a leaflet produced by the Museum of London Docklands. When you follow the instructions and tear along the perforated lines you have ten cards for each of the rivers; the Thames, Neckinger, Tyburn, Walbrook, Westbourne, Lea, Peck, Fleet, Effra and Wandle, which then can be used in a Top Trumps style card game. So the Thames will beat the Neckinger on length, 215 miles compared to 3 but the Neckinger has a greater pong rating 80 points for stinkiness compared to just 38 for the Thames.

It’s a lovely idea, and the map is very much secondary to the text/cards on the reverse.

An earlier map of London covering the same area shows how early London’s rivers had been hidden away.

Map of the country twelve miles round London 1847 (E) C17:40 (72)

Of the ten on our Museum map only the Thames and Lea (the river that divides the counties of Hertfordshire and Essex), are visible, the others are either too small to show or had already been drained and forced underground by the time C. Smith & Sons made their map in 1847.

Map staff would like it known that they resisted the urge to play the game!
