The "Cross and Crown" one I recognize the drawing from a book my mom had, copyright 1980. They may be from the 1930's originally, but the envelopes would be yellow, and so would the tape and/or glue that the pictures are on the envelopes with. You are talking about 80 years plus. If you invest in the book "5500 Quilt Block Designs" for about $20.00 used, you will get a much better deal.
