This postcard is unused so there is no postmark to help pinpoint the year the photos were taken. However, if you watch the Freeman’s Amusement Center Fire video you can see the rides featured in the bottom photo at the end of the video in scenes showing the post-fire reconstruction. That makes me think that the bottom photo was likely shot at least two months following the June 1955 fire and maybe within the following two or three year period. If you magnify the postcard you can also see a sign for Beachcomber Bar.
Funtown U.S.A. Circa 1955-60
