The customer had an antique print in an antique Hogarth frame (black with gilt detail) which he wanted to pair with another unframed print of a similar style.
Although there are some modern Hogarth style mouldings, they are generally much narrower than on the old frame and so were unsuitable in this case, and whilst there are some frame makers who are still able to make these traditional frames from scratch (not me!) a new hand carved and gilded frame would cost hundreds of pounds.
However – there is a third way! I bought an old, larger, second hand frame online and re-cut it to the same size as the existing frame. Whilst not quite identical it was close enough to create the required effect at a reasonable cost.
