Design for an altar (home altar?)

Design for an altar (home altar?) on which there is a Louis XIV tabernacle with a dome in the centre, on which is the pelican with its young; on the door is Jesus hanging on the cross. On the left and right, on each corner of the altar, there is a kneeling angel. The retable consists of a framed panel with a rocaille crown around a base in the form of an obelisk bevelled at the top, on which the Lamb is depicted lying on the Book with Seven Locks. Clouds and an aureole are depicted behind this.
