<div>This is a fairly simple technique in leaflet. All I
have done with the graphhopper example I showed on the
blog was to add another map layer instance to the template
code provided by the graphhopper install.<br>

If you want something which is not desperately difficult to
understand showing mulitple historical map layers with
transparency in leaflet, I suggest having a look at Will
Phillips SM-Nottingham site: e.g.,<a moz-do-not-send="true"
href="http://osm-nottingham.org.uk/?z=16&lon=-1.15355&lat=52.96680&bgl=OSM,0.38,17;Salmon,1,16">http://osm-nottingham.org.uk/?z=16&lon=-1.15355&lat=52.96680&bgl=OSM,0.38,17;Salmon,1,16</a>.
Chris Hill has also written some useful intro stuff about
using leaflet with historical maps: <a
moz-do-not-send="true"
href="http://chris-osm.blogspot.co.uk/2014/04/images-to-map-overlays.html">http://chris-osm.blogspot.co.uk/2014/04/images-to-map-overlays.html</a>.</div>

thanks, that's a good start.<br>
