This Gustav Stickley drop front desk produced between 1904 and 1907 according to the red decal on the back. This differs from the #729 that we usually see in that it has a solid wood paneled drop front. The version that normally surfaces has a veneered drop front that typically has veneer issues.
I have heard this referenced as an earlier version but the paneled version still shows in the 1912 catalog. I guess I’m surprised that they don’t show up more often but from my experience this desk is quite rare, especially in this black finish.
The condition is excellent with the original finish and color. Measures 43″ tall x 36″ wide x 14″ deep.
