Cries of London engravings - Francis Wheatley

Three framed prints from the Cries of London series.  Plate 7, Plate 8, Plate 13.

All seem to be in great condition. Minor spotting on the border that doesn't affect the images themselves. The colors on them are very light. Didn't notice the color at first when I bought them but the black lines are dark so I don't believe it's faded at all.

I've seen full color reproductions and some that are completely just black and white. I've not seen any similar to mine that are so lightly colored. The colors appear a bit more intense in the image attached.

I know very little about them and I've not been able to find much detail. I've seen them sell as cheap reproductions and $400+ from English antique print sellers. Any help would be appreciated. Thank you.
