I just did some research and found out the Three Framed Prints are by Turner Cydney. The smaller of the 3 is called 'Garden Party'. According to the old yellowed price tag on the back of the smaller one it was sold by The May Co (aka Macy's today) in Dept 21 for $2.98. A few other of his similarly framed prints are listed on ebay for $39.99 each.
Not bad for a trip to a Thrift Store one snowy Black Friday!
