Letter written to the Rev. J.E. Vonkenberg, chairman of the Dutch Federation of Young Men’s Associations on Reformed Principles. In the letter Kuyper thanks Vonkenberg for the speech he had delivered on Kuyper’s seventieth birthday. He also expresses gratitude for the federation’s birthday gift—an album with a calligraphic calfskin cover containing (in an elegant hand) the names of the administrators of the federation and its provincial branches, the number of the federation’s associations, and the total number of its members. The album was made by J.J. van Blitterswijk Jr., artist and member of the Young Men’s Association “Nathanaël” in Haarlem.

A bronze birthday medal was sent along with the letter. The medal (55mm.; medalist, J. van Goor; bronze, C.J. Begeer, Utrecht) bears Kuyper’s effigy on the front side and, on the reverse side, his name and the dates 1837 and 1907 emblazoned between an oak and a laurel leaf; see front cover of the bibliography.
