During a visit in October 2016 to the Dutch "BMX MUSEUM" of Old Skool BMX'er Mike Janssen, I saw the following objects that I thought were worth while showing to you all. Shown below the BMX MUSEUM logo with in front a prototype ONE Bicycles frame, donated to the museum by Christian v.d. Groenendaal, owner of ONE Bicycles.
EPPO magazine was a childrens magazine that was issued at schools. In the '80's EPPO started a BMX team in cooperation with former moto-cross Champion Pierre Karsmakers. Here two pictures of concept drawings for rider uniforms and painting the team bus. All exposed at the BMX MUSEUM.
During our October visit we also did find these cards issued by HUFFY Bicycles (1983). I never saw those before and I think are kind of unique. Just a serie of cards to give you all an impression.
