Size ± 2 meters. Exclusively drawing envelopes (± 50x40 cm.), mostly numbered (list of work numbers present: see Appendix). In it only numbered final design and execution drawings (calques), by number with drawing lists in the envelopes. No correspondence.
In addition a drawer with ± 100 training drawings of the TH Delft (1912-1920), mostly large format. Incidentally, the NAI already has the "Van der Steur Collection"; a collection of travel sketches by Dutch architects, presented by the BNA to A.J. van der Steur on his departure as BNA chairman in 1953. The archive section Leliman (1898-1921; list: see Appendix) has already been sequestered by Chr. Smeenk (librarian of Architecture Delft), who is working with C. Schade on a publication on the work of J.H.W. Leliman. This volume consists only of blueprints and specifications and will soon be transferred to the NAI by Smeenk, along with a number of travel sketches by J.H. Leliman (the father) from 1840-1850.
A small part of the J.H.W. Leliman archive is already at the NAI: a number of drawings previously removed by D. van Woerkom and the material recently obtained from the Leliman heirs from France (framed sketches and a folder of children's drawings).
Incidentally, J.H.W. Leliman's library and a number of sketches have been donated by the widow to Bouwkunde Delft (information: Chr. Smeenk).
