Example of the size:

“Assortment of Five Jeeps, all die cast metal with rolling wheels, Still in the Original Unopened Variety Store Display Card! All metal construction with rubber wheels similar to Matchbox. Accurate Jeep details! The jeeps were made by Midgetoy in Rockford Illinois from the mid 1950’s into the 1960’s. The package is dated 1980. The blister card packaging was done throughout the 1970’s to use up remaining stock before closing down in 1982. Same size as the ones in the Store Display Package of 36. We pull these cards out of a wholesale box of 36 cards. You get it just like the Dime Store had them! If you buy more than 1 card we will try to give you a diverse color assortment.

The set also contains a pair of Gas pumps made to the same scale as the cars! This set is one of many classic toy items found from unsold merchandise left in the back rooms of an old dime store distributor. The ultimate toys for owners of Diggers or Claws coin op prize machines! Ideal for the Jeep fanatic! No nicks, No scrapes, No missing wheels, No rust, No dings. The display card is slightly yellowed and warped around the edge, otherwise Perfect Unopened Condition. Original Package ~ Colors Vary.”
