Dear Sir
I herewith send you the best transfer that can be got with your Asphalt solution. I have also tried it with several other things but have not succeeded in getting a full impression to transfer to a new plate however I will be glad to try any other stuff you may think of.
My opinion is, the Asphalt will never do alone as it is too adhesive in its property to come out of the work so as to give a firm clear impression.
I am dear Sir Yours respectfully
Alexander Banks
