Very detailed Frankfurt ring that features such landscapes as the Römer, Paulskirche, Euro tower, Messe Turm, Alte Oper, Eiserner Steg, working man, and Alte Nikolaikirche.
If you need another size please contact me.
More Skyline - Cityscape rings here.
Please double check your size. It is important, because these rings are pretty tall (aprox 10mm high) and maybe feels tighter then the usual rings.
