This is a new old stock (NOS) clear polycarbonate marketing literature rack holder. It's leaflet sized (holds up to 4 1/4" wide leaflets). It can be mounted to the wall or stands on desktop. Includes all hardware for both options. The "stand-tall" name is because it has a plastic support to keep the brochures standing upright. The capacity is 2 5/8". The packaging claims it is unbreakable -- polycarbonate is stronger than acrylic.
This is useful for placing information brochures in a retail setting or along side artwork. I bought it to place descriptions of my artwork during exhibits, but the gallery had other options in place.
This Deflect-o Model 53601 stand is Made in the USA. It was purchased about 25 years ago but never used. Still in the box (box is a bit worn).
