Appears to be old Victorian Trade Card sheets

These were found in an old Photo album. They appear to be old Scrap Trade Cards. The first FEDERICO VARELA CO. MALAGA, The second VIRIATO OLIVER DENIA, The Third, W.C. BEVAN @ Co. and the last PEDRO A. De AGUIRRE MALAGA. They appear to have what looks to be a Lace gold paper Doily attached to the back. Unknown exact year believe to be around the late 1800's to 1900's. Still researching just wanted to share. They measure around 9 " x 6-3/8 " Any help would be appreciated.
