Here are three photos which will surely be of interest. They are from the wonderful book: Carriages of the Past;Victorian postcards of the collection of Mario Broekhuis. Published in 1998 by Wim Knijnenburg Produkties. The first thumbnail is of Alva 113 Preferant, yes, that is 113, a very early photo of an Approved Friesian stallion. He is the fifth of six approved sons by De Regent 32 Preferant, son of Prins Hendrik 24. Of the six sons, he is the only to produce approved sons of his own, two, Oom 119 and Stefanus 124.
The next two photos are also of Friesians, shown in front of the traditional Frisian sjees. Unfortunately, these photos are in a high resolution so that the text beneath them can be read, so the enlarged version may take some time for them to load properly.
