This Mid Century envelope style clutch purse by Andé has an optional long goldtone S chain shoulder strap that tucks inside when not in use. It's generously sized at 11-1/2 inches wide by just over 7 inches high. A magnetic closure is concealed under the flap. The interior is lined in black ribbed satin with a back wall pocket in contrasting eggshell white ribbed satin. The purse is in excellent vintage condition, clean with no damage. I've lightened the photos a little to better show the tucked details on the lower front flap.
