I've eight drinking glasses labelled for ┼fors, and two labelled for Boda-┼fors, in the same colour but with different shapes. Both bear the same Bertil Vallien designer label to the base.
One of the ┼fors glasses still has its original paper wrapping, stamped with BV 120 Blň (BV presumably for Bertil Vallien).
They were leftover stock from a glass shop that closed c.1974, which gives a cap to the latest possible date they could have been designed and produced, with 1963 being the earliest as this is when Vallien started with ┼fors / Boda...
...but does anyone a better idea exactly when they hail from? I don't know if the different labels indicate different periods, or if they were used concurrently to market designs under different names. Because the designer labels are identical, presumably they had concurrent use.
Thanks for looking.
