Double-tag events in two-photon collisions are studied using the L3 detector
  at LEP centre-of-mass energies from $\sqrt{s}=189~\mathrm{GeV}$
  to 209~GeV. The cross sections of the
  $\mathrm{e^+e^-} \rightarrow \mathrm{e^+e^-} hadrons$ and 
  $\gamma^*\gamma^* \rightarrow hadrons$ processes 
  are measured as a function of the photon virtualities, $Q^2_1$ and $Q^2_2$,
  of the two-photon mass, $W_{\gamma\gamma}$, and of the variable
  $Y= \ln ( W^2_{\gamma\gamma}/{Q_1 Q_2})$, for an average photon virtuality
  $\langle Q^2 \rangle = 16~\mathrm{GeV^2}$. The results are in agreement 
  with next-to-leading order calculations for the process 
  $\gamma^* \gamma^* \rightarrow \mathrm{q \bar{q}}$ in the interval 
  $2 \le Y \le 5$.  
  An excess is observed in the interval $5 < Y \le 7$, corresponding to 
  $W_{\gamma\gamma}$ greater than 40~GeV . This may be interpreted as a sign 
  of resolved photon QCD processes or the onset of BFKL phenomena.
