I don't expect there will be a Kulmbach fair in 2021, as our Kulmbach is, in terms of logistics, just an appendix to the beer-week (I'd prefer it vice versa). They won't erect the hall/tent just for three days. And most collectors, unfortunately, are in or near the covid-risk-group with regard to age.
As Ed I think there might be a chance for 2022, the beer-week being an annual affair.Keep painting.
