Historical images depicting generic people

[barefootliam]

I've posted a number of images from my own commercial Web site (fromoldbooks.org, hope it's OK to mention it) and a lot of them are woodcuts, often with people in them.

 

The people are usually generic, e.g. to give a sense of scale in an engraving of a building, or two Victorian gentlemen comforting a forlorn-looking boy at a funeral (to illustrate a story, fiction). I have done extensive research to make sure the pictures are not encumbered in any way.

 

If I say there are 3 people in th funeral engraving then I have to upload a model release in order to sell the imate as royalty-free.

 

if I say  there are zero people (which is what I have done so far) I fear people won't find the picture.

 

Should I upload a "release" that simply says no release is needed?
