The regular pictures can be transferred to wood, metal, painted surfaces, etc., but instead of soaking them in water alone as you used to with the toy pictures you give the face of them a very thin coat of a good, quick drying, rubbing varnish which you can get at a paint store, or better, use a transfer varnish which you can buy of the above company for 35 cents for a 1/2 pint can.
After you have applied the varnish to the face of the picture let it dry until it is very tacky; now put the face of the transfer down on the surface, wet it with water on a sponge and roll it down hard with a felt roller.
In a couple of minutes wet the paper again thoroughly with water and peel it off; roll it down at once with a wet felt roller and tap it off with a piece of chamois skin. After the design or picture has dried for 20 minutes or so, the varnish around it can be removed by dampening it with dilute turpentine, ammonia or, better, with a detergent made of equal parts of turpentine and crude oil and immediately rubbing it away lightly and quickly with a dry, soft rag.
After the picture has been transferred as above, it should be given one or more protecting coats of varnish the next day.
