Unknown Luft 'tinnie'

I've never seen this plastic tinnie before. DLV? Any clue what the significance is?

Hi Andrew, not seen this particular one before, but it is likely to be a donation badge from the DLV = Deutscher Luftsportverband, where they will have run collections to fund their activities. Quite nice really, are there any markings on the back? Cheers, Torsten.
