GMB's study (commissioned by the Guggenheim paid for by the Basque government, and conducted by Gestec, IBS and Peat Marwick) projects an annual income of 1.4 billion pesetas ($14 million at that time) based on generous private support (supplying up to 40- 50 percent of the museum's annual budget and in expectation of healthy attendance (estimated at 694 547 visitors annually, consisting of24 percent from the province, 32 percent from nearly regions, and the remaining 43 percent Spanish and foreign). The GMB's estimated multiplying effect on the Basque economy would raise annual spending in the region by $35 mi lion, plus generate S4 million in taxes. But Zallo and Gaviria argued that the report seriously overestimates attendance, as well as potential income and favorable economic impact overall Factors they feel were inadequately considered include: Bilbao's lack of touristic appeal, the Basque Country's tiny art audience and undeveloped cultural infrastructure (only four or five struggling commercial galleries show contemporary art. and only a few modest arts institutions exist): an Spain's meager history of private giving and relatively law museum attendance (only the Prado. Reina Sofia and Dali museums regularly receive more than a half. million visitors). Likening the project to a fatal triple sontiersault without a net, they the GMB as a vastly disproportionate expense unlikely to aileviate the Basque Country's severe political and economic difficulties let cultural needs cither on a symbolie alone or practical level.
