The West Ham United Mercurycards Presentation pack was first advertised in the popular “90 minutes” football magazine. Fusilatelist is the name given to collectors of Telephone Cards. The craze to collect these magnetically encoded pieces of plastic first started in Japan and quickly spread to Europe with some cards worth many times their face value. 
Mercurycards were first issued in July 1988 when Mercury Communications Ltd launched its payphone service with an extravaganza at Waterloo Station in London. The Hammers featured in this 1990-91 Football League season first edition set, limited to just 4,000 packs and retailed at £7.99 which contained the clubs’ £2 and £5 Mercurycards.
