When I opened this drawing’s image file and viewed this drawing, I realized it was something special. Zoom in on the drawing and take a good look. You will surely agree with me; it is an art-piece. I feel it is worth sharing in spite of this Blog’s name.The draftsman’s initials are located at the lower right corner of the drawing. I am recording the initials as part of the database I am using to catalog the image files of the scanned drawings from the UPHS  Collection. I hope we can put names to the initials and pay due  respect to these craftsmen. I welcome suggestions as to how we  might be able to identify them.
