Concurring Opinion by
Judge Blatt :I concur in the opinion of the majority. 1 would have preferred, however, to make clear that this decision need not, and, in my opinion, should not, affect our holding in Faith United Presbyterian Church v. Redevelopment Authority, 7 Pa. Commonwealth Ct. 490, 298 A. 2d 614 (1972), where the introduction of photographs of comparable properties was also considered.
