Well, all four pieces above is Forejtová :-) but to be sure, I am downloading two other
Note please different quallity of pieces.
Forejtova figure is not very rare here, but complete Forejtova design as cetrepiece with frog and bowl I have seen only in Marcus' collection and in CGR.
Possibly figure will fit to standardised frog, I did not try it yet but I will.
The size should help - my pieces are about 16 cm height and 5.5 cm is maximum diameter of bottom.
