Vintage framed signed/dated floral artwork

Set of two beautiful vintage etched Iris floral framed/matted art pieces. Signed/numbered. First piece is titled Iris III numbered 373/500 with artist signed initials Second piece is titled Iris IV numbered 281/ 500 with artist initials. These look like David Allgood art pieces, but found another listing of a green Iris art piece that states the artist as L. Lanier. I do not know who the actual artist is but they are beautiful pieces with an ombre effect. 12 1/2" x 9" Nice quality gold frame. There are a few scratches on the gold frame but that is typical for a vintage piece. hanging wire is attached
