The CLEO II detector at the e(+)e(-) storage ring CESR has been used to search for two-photon production of the f(J)(2220) decaying into pi(+)pi(-). No evidence fora signal is found in 4.77 fb(-1) of data and a 95% C.L. upper limit on [Gamma(gamma gamma)B(pi+pi-)](fj(2220)) of 2.5 eV is set. If this result is combined with the BES Collaboration's measurement of f(J)(2220) --> pi+pi- in radiative J/psi decay and the recent CLEO result for [Gamma gamma gamma B-KS0S0](fJ(2220)), a 95% C.L. lower limit on the stickiness of 102 is obtained. This result for the stickiness provides further support for a substantial neutral parton content in the f(J)(2220). [S0031-9007(98)07326-8].
