We thank you for the interest that you have manifested in us, and for your offer to open the Stedelijk Museum to an experiment by the SI.
Unfortunately, it is impossible for us to envision any sort of restriction on the anticipated exposition. We know the obstacles that you face at this moment. But our role, as you certainly know, is to safeguard the totality of our research, not to have us substituted for specialists in the research of socio-economic arrangements. Consequently, we inform you that you can foresee another assignment for rooms 36 and 37 starting 30 May [1960]. The situationists will not be in a position to make use of them on that date, nor later on.
Please accept, dear sir, our best remembrances.
