We use the CLEO detector at the Cornell e{sup +}e{sup -} storage ring, CESR, to search for the two-photon production of the glueball candidate f{sub J}(2220) in its decay to K{sub S}K{sub S}. We present a restrictive upper limit on the product of the two-photon partial width and the K{sub S}K{sub S} branching fraction for this narrow resonance. We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on the stickiness indicates that the f{sub J}(2220) has substantial glueball content.
