Forest Cards Cup and Trophies Vorwaerts Frankfurt/Oder

Forest Cards Series 2 Cups and Trophies card #20. Rather unusual both in its content and in that the card is untitled, it depicts a vase presented to the club by the East Germans.
I have to confess I know pretty much nothing about this card, and I haven't seen any others from this collection. If anyone knows anything about this set or series 1 please get in touch.
The UEFA Cup first round second leg in East Germany was played on 28 September 1983, Forest winning 1-0 thanks to an Ian Bowyer goal in front of a crowd of 18,000. Forest's then opponents now ply their trade in the Oberliga Nordost, Germany's fifth tier, under the name 1.FC Frankfurt.
Update 19/01/16: Trevor Gillies has been in touch to say the cards were issued by the club in conjunction with Repro House and Apollo Soft Drinks (part of Home Brewery, Daybrook) and given to season ticket holders in 1984. In all there are three series of 20 cards.
