Father and son Percy and Ray Terry show off just a selection from their badge collection which they wear on their caps every day at the Show.
The two cleaners have been collecting pins and badges at Farnborough Airshows since 1992. "Many firms are very kind and when we approach them they offer us badges and pins to add to our caps," said 70-year-old Percy.
The souvenirs remind the Terrys of the great atmosphere at the air show.
Unusual items in their collection include a white Concorde badge - there were only 200 made - currently worth more than $300 to American collectors.
