Vintage Antique Glass framed LA Concepcion Murillo

Murillo Paintings Reproduction and Biography

Murillo was Born in Seville. I think this is original or oil reproduction. It has antique wood frame looks real old fame with Glass. Vintage Antique LA Concepcion framed print w/ glass on canvas. It has a small piece of old paper on back of frame Saying
LA CONCEPCION Murillo (1616-1682)
Museo 'del Prado ( Madrid )
D.L SS.. 328-67
Procedimiento Oleographico Patentado
Madrid-27 (Espana). The painting itself is on this heavy paper feel looks glued on to this canvas or paper or cotton or string net woven design looks like woven design glued together to make strong background for the painting to be glued or put onto that. But painting or reproduction? But also the heavy paper has this bumpy painting design like it was painted. Anything you can tell about what it says on the small piece of paper with all those writings and what it means. I get it says Murillo was the painter but was it it done in 1616-1682?or housed at the Museo del Prado during those times? Or what Murillo and the dates mean next to name?
