The design on this mug shows the finger spelling alphabet which people with a hearing impairment use as a means of communication. Breakthrough Deaf-Hearing Integration is the organisation that designed the mug. Now called DeafPLUS, this charity has its London base in Whitechapel. They point out that 'Deafness does not have the universal appeal or visibility to attract funding, yet it affects 14.5% (or 9 million) people in the UK.'
