Vtg Chateau Frontenac & Porte Saint Louis Quebec Ink Drawings on Fabric 1967 Set

Vintage Chateau Frontenac & Porte Saint Louis Quebec City Framed Watercolor Ink Drawing Colorized Sketch Painting on Fabric Linen? Cotton? 1967 Mid Century Modern, MCM. in very good pre owned vintage 1967 condition. Expected aging. Both signed by the same artist, but I cannot identify the signature. I believe these are ink drawings, but they also have areas that appear to be watercolors. Not an art expert, but these are just beautiful with that very 1967 MCM vibe. Both in gold metal frames with glass. Approx msmts in inches: Prints 9.75 length x 4 width. Frames 12.5 length x 6
