Data taken with the ALEPH detector at LEP1 have been used to search for γγ production of the glueball candidates f0(1500) and f(J)(1710) via their decay to π+π-. No signal is observed and upper limits to the product of γγ width and π+ π- branching ratio of the f0(1500) and the f(J)(1710) have been measured to be Γ(γγ→f0(1500)) · BR(f0(1500) → π+π-) < 0.31 keV and Γ(γγ → f(J)(1710)) · BR(f(J)(1710) → π+π-) < 0.55 keV at 95% confidence level.
