All models have a correct analytical structure with a minimal set of well known singularities. For the first time an effective two-pion intermediate coulombic bound state (pionium) was included into GVMD for nucleon formfactors. For the proton charge radius an estimate derived from our best fits is as follows: r_E^p [\\rm fm] = 0.897 \\pm 0.002(exp) \\pm 0.001(norm) \\pm 0.003(models).
