This might be a little more obscure than most. Grell for many years was supplied with models made by High Speed, and I presume this is early enough to think this is High Speed. High Speed provided many Eastern European makes and models for Grell releases. Grell appears to be a promotional model supplier, the vast majority of their issues are themed for various beer brands and soft drinks, and occasionally sports teams. Some are packaged in rather adult themed packaging, which would be why I can't show here some of the ones I've picked up over the years that are still in package. Grell has / had a few surprises, including a number of the High Speed issues commonly referred to as Readers Digest showing up among their issues. It is surprises such as those that make Grell interesting to me to collect...there's a lot of cross-pollination!
