Artist Karen Hatzigeorgiou has posted some charming public domain images of woodwind instruments at her website, like this lovely clarinet. The others are in a similar pen-and-ink (or is it some kind of etching?) style.
Click here for the whole collection. Or almost the whole collection. At first I was disappointed not to find a saxophone, but it’s just misfiled here.
Again, these are public domain images, which means you are free to use them to your own nefarious ends. Thanks, Karen!
