After researching this, I did not find any information on the artist. The artist's that the paintings were taken from by the W.T. Burger co, are not listed in any art data base. I did find information on the company.
The Thanhardt-Burger Corp. had its beginning in 1927 when Henry Thanhardt, who had immigrated to the United States from Austria and settled in Chicago, came to La Porte to start a framing business. Thanhardt had brought some pieces of fine art from Europe, and he was searching for a place to have them framed.
He discovered the Indiana Molding and Frame Co. in La Porte and decided to set up a similar business, also in La Porte, which he called The Leader Manufacturing Co. He was joined in this business in 1928 by Walter Burger, and, in 1933, the company was incorporated as the Thanhardt-Burger Corp.
In 1946, the W.T. Burger Co. was founded to provide art - both original and reproduction - for the company's frames. We believe that the prints with the "Reofect Paintings" trade name were probably not made until after 1933 - and maybe not until after 1946 - and their manufacture did not continue much after mid-century because the process to make them was prohibitively expensive.
They were typically retailed in department stores and art galleries and originally sold in the $150-$300 range. We further believe from our research that this was a high-tech (for the day) oil-based "photocopy" process that was surfaced with a special varnish that made the print look like an oil painting.

Does your painting look like it is an original oil painting or one of their reproduction works?
